1,888,515 | A Complete Guide to Safe and Effective Plumbing Repair | Plumbing repairs are essential for maintaining the functionality and safety of your home’s water... | 0 | 2024-06-14T11:53:36 | https://dev.to/affanali_offpageseo_a5ec6/a-complete-guide-to-safe-and-effective-plumbing-repair-i3h |
Plumbing repairs are essential for maintaining the functionality and safety of your home’s water system. Whether you’re tackling a simple fix or a more complex issue, understanding the basics of safe and effective plumbing repair is crucial. This guide provides a comprehensive overview of common plumbing repairs, safety tips, and best practices to ensure your repairs are successful and long-lasting.
Understanding Common Plumbing Issues
Leaky Faucets
Leaky faucets are a common issue that can lead to water waste and higher utility bills. Typically, the problem lies with worn-out washers, O-rings, or valve seats. Replacing these components can often resolve the leak.
Clogged Drains
Clogs can occur in sinks, showers, and toilets due to the buildup of hair, grease, soap scum, and other debris. Using a plunger, drain snake, or chemical drain cleaner can help clear minor clogs. For persistent issues, professional intervention may be necessary.
Running Toilets
A running toilet can waste a significant amount of water. Common causes include a faulty flapper, fill valve, or flush valve. Replacing these components can usually fix the problem.
Low Water Pressure
Low water pressure can result from various issues, including clogged pipes, faulty pressure regulators, or problems with the municipal water supply. Identifying the root cause is essential for proper repair.
Water Heater Issues
Problems with water heaters, such as insufficient hot water or strange noises, can stem from issues with the thermostat, heating element, or sediment buildup. Regular maintenance and timely repairs can extend the lifespan of your water heater.
Safety Tips for Plumbing Repairs
Turn Off the Water Supply
Before starting any plumbing repair, always turn off the main water supply to prevent flooding and water damage. Locate the shut-off valve and ensure it’s completely closed.
Use the Right Tools
Using the correct tools for the job is crucial for effective and safe repairs. Common plumbing tools include pipe wrenches, pliers, plunger, plumber’s tape, and a drain snake. Ensure you have all necessary tools before beginning your repair.
Wear Protective Gear
Protective gear, such as gloves, safety goggles, and knee pads, can prevent injuries during plumbing repairs. Always wear appropriate gear to protect yourself from chemicals, sharp objects, and other hazards.
Follow Manufacturer Instructions
When repairing or replacing plumbing fixtures and components, always follow the manufacturer’s instructions. This ensures proper installation and prevents voiding warranties.
Be Cautious with Chemical Cleaners
Chemical drain cleaners can be effective for clearing clogs but can also damage pipes if used excessively. Use them sparingly and follow the instructions carefully. Consider mechanical methods like plungers or drain snakes as safer alternatives.
Best Practices for Effective Plumbing Repairs
Proper Diagnosis
Accurate diagnosis of the problem is the first step in effective plumbing repair. Take the time to identify the root cause of the issue rather than just addressing the symptoms.
Quality Materials
Using high-quality materials and parts for repairs ensures durability and longevity. Avoid cheap materials that may lead to recurring issues and additional costs.
Correct Installation Techniques
Follow proper installation techniques to ensure a secure and leak-free repair. This includes using plumber’s tape on threaded connections, tightening fittings appropriately, and ensuring proper alignment of components.
Regular Maintenance
Regular maintenance can prevent many common plumbing issues. Schedule annual inspections, clean drains periodically, and address minor issues promptly to avoid major repairs.
Know When to Call a Professional
While DIY repairs can be effective for minor issues, it’s important to recognize your limits. For complex or critical repairs, hiring a professional plumber like MDTech Plumbing Repair ensures the job is done safely and correctly.
Frequently Asked Questions (FAQs)
How can I prevent plumbing issues?
Prevent plumbing issues by performing regular maintenance, avoiding the disposal of grease and large debris down the drains, insulating pipes in cold weather, and addressing minor issues promptly.
What should I do if I have a plumbing emergency?
In a plumbing emergency, turn off the main water supply to prevent further damage. Contact a professional plumber immediately for emergency services. Avoid attempting complex repairs yourself.
Are chemical drain cleaners safe to use?
Chemical drain cleaners can be effective for minor clogs but can damage pipes if used excessively. Use them sparingly and follow the instructions. Consider mechanical methods like plungers or drain snakes as safer alternatives.
How often should I inspect my plumbing system?
It’s recommended to have your plumbing system inspected at least once a year. Regular inspections help identify potential issues early and ensure your system is functioning efficiently.
Can I handle minor plumbing repairs myself?
Yes, minor plumbing issues like fixing a leaky faucet or unclogging a drain can often be handled with basic knowledge and tools. However, for more complex or critical issues, it’s best to hire a professional to avoid costly mistakes.
What are the benefits of hiring a professional plumber?
Hiring a professional plumber ensures accurate diagnosis, quality repairs, and adherence to safety standards. Professionals have the expertise, tools, and experience to handle complex issues and prevent recurring problems.
Conclusion
Safe and effective plumbing repair requires a combination of proper diagnosis, the right tools and materials, and adherence to safety guidelines. By understanding common plumbing issues and following best practices, you can tackle minor repairs confidently and effectively. However, for more complex or critical repairs, professional services like [MDTech Plumbing Repair](https://appliancesrepairmdtech.com/plumbing-repair-service/) provide the expertise and reliability needed for thorough and safe repairs.

1,888,514 | Reading Data from the Web | Just like you can read data from a file on your computer, you can read data from a file on the Web.... | 0 | 2024-06-14T11:52:08 | https://dev.to/paulike/reading-data-from-the-web-1l6 | java, programming, learning, beginners | Just like you can read data from a file on your computer, you can read data from a file on the Web. In addition to reading data from a local file on a computer or file server, you can also access data from a file that is on the Web if you know the file’s URL (Uniform Resource Locator—the unique address for a file on the Web). For example, [www.google.com/index.html](www.google.com/index.html) is the URL for the file **index.html** located on the Google Web server. When you enter the URL in a Web browser, the Web server sends the data to your browser, which renders the data graphically. Figure below illustrates how this process works.
For an application program to read data from a **URL**, you first need to create a URL object using the **java.net.URL** class with this constructor:
`public URL(String spec) throws MalformedURLException`
For example, the following statement creates a URL object for [http://www.google.com/index.html](http://www.google.com/index.html).
```
try {
URL url = new URL("http://www.google.com/index.html");
}
catch (MalformedURLException ex) {
ex.printStackTrace();
}
```
A **MalformedURLException** is thrown if the URL string has a syntax error. For example, the URL string “[http:www.google.com/index.html](http:www.google.com/index.html)” would cause a **MalformedURLException** runtime error because two slashes (**//**) are required after the colon (**:**). Note that the **http://** prefix is required for the **URL** class to recognize a valid URL. It would be wrong if you replace line 2 with the following code:
`URL url = new URL("www.google.com/index.html");`
After a **URL** object is created, you can use the **openStream()** method defined in the **URL** class to open an input stream and use this stream to create a **Scanner** object as follows:
`Scanner input = new Scanner(url.openStream());`
Now you can read the data from the input stream just like from a local file. The example in program below prompts the user to enter a URL and displays the size of the file.
The program prompts the user to enter a URL string (line 8) and creates a **URL** object (line 11). The constructor will throw a **java.net.MalformedURLException** (line 21) if the URL isn’t formed correctly.
The program creates a **Scanner** object from the input stream for the URL (line 13). If the URL is formed correctly but does not exist, an **IOException** will be thrown (line 24). For example, [http://google.com/index1.html](http://google.com/index1.html) uses the appropriate form, but the URL itself does not exist. An **IOException** would be thrown if this URL was used for this program. | paulike |
1,888,513 | How to Deploy an Express.js App on GitHub Pages Using GitHub Actions | How to Deploy an Express.js App on GitHub Pages Using GitHub Actions Deploying an... | 0 | 2024-06-14T11:51:56 | https://dev.to/sh20raj/how-to-deploy-an-expressjs-app-on-github-pages-using-github-actions-4h0f | webdev, javascript, github, githubpages | # How to Deploy an Express.js App on GitHub Pages Using GitHub Actions
Deploying an Express.js app on GitHub Pages might sound challenging at first, but with the right tools and steps, it becomes a seamless process. GitHub Pages only supports static sites, so we need to convert our dynamic Express.js app into static files. In this article, we'll walk through the steps to achieve this using Webpack for bundling and GitHub Actions for automation.
## Step 1: Set Up Your Express.js App
First, ensure you have an Express.js app. If you don't have one, you can create a simple app as follows:
```bash
mkdir express-app
cd express-app
npm init -y
npm install express
```
Create a file named `server.js`:
```javascript
const express = require('express');
const path = require('path');
const app = express();
app.use(express.static(path.join(__dirname, 'dist')));
app.get('*', (req, res) => {
res.sendFile(path.resolve(__dirname, 'dist', 'index.html'));
});
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
```
## Step 2: Set Up Webpack
To bundle your app into static files, we'll use Webpack. Install Webpack and its dependencies:
```bash
npm install --save-dev webpack webpack-cli babel-loader @babel/core @babel/preset-env @babel/preset-react
```
Create a `webpack.config.js` file:
```javascript
const path = require('path');
module.exports = {
entry: './src/index.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env', '@babel/preset-react'],
},
},
},
],
},
};
```
In your `package.json`, add a build script:
```json
"scripts": {
"build": "webpack --mode production"
}
```
## Step 3: Create Your React Components
If you're using React with Express, create a simple React component. Create a directory `src` and an `index.js` file inside it:
```javascript
import React from 'react';
import ReactDOM from 'react-dom';
const App = () => {
return (
<div>
<h1>Hello, Express and React!</h1>
</div>
);
};
ReactDOM.render(<App />, document.getElementById('root'));
```
Add an `index.html` file in the `src` directory:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Express App</title>
</head>
<body>
<div id="root"></div>
<script src="bundle.js"></script>
</body>
</html>
```
## Step 4: Configure GitHub Actions
To automate the build and deployment process, create a GitHub Actions workflow. In your repository, create a `.github/workflows/deploy.yml` file:
```yaml
name: Deploy Express.js App to GitHub Pages
on:
push:
branches:
- main # Trigger the workflow on push to the main branch
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout repository
uses: actions/checkout@v2
- name: Set up Node.js
uses: actions/setup-node@v2
with:
node-version: '16'
- name: Install dependencies
run: npm install
- name: Build project
run: npm run build
- name: Deploy to GitHub Pages
uses: peaceiris/actions-gh-pages@v3
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
publish_dir: ./dist
```
## Step 5: Ensure Your Static Files Are Managed Properly
Make sure the `dist` directory is included in your `.gitignore` file, so it's not tracked in your repository:
```gitignore
/dist
```
## Step 6: Commit and Push Your Code
Add, commit, and push your code to GitHub:
```bash
git add .
git commit -m "Set up deployment to GitHub Pages"
git push origin main
```
## Conclusion
By following these steps, you can convert your Express.js app into static files and deploy it to GitHub Pages using GitHub Actions. This approach leverages Webpack for bundling and GitHub Actions for CI/CD, providing a streamlined deployment process.

Step-by-Step Guide to Safe Appliance Installation
Preparing for Installation :
1. Read the Manual:
Start by thoroughly reading the manufacturer's installation manual. This document provides specific instructions and safety warnings tailored to your appliance.
2. Measure Your Space:
Ensure that your appliance will fit in the designated area by measuring the height, width, and depth. Compare these dimensions with the appliance's specifications to confirm a proper fit.
3. Check Electrical and Plumbing Connections:
Verify that your home’s electrical and plumbing connections meet the appliance's requirements. Ensure that outlets, water supply lines, and drainage systems are accessible and in good condition.
Installing the Appliance
1. Turn Off Utilities:
Before starting the installation, turn off the relevant utilities. This includes shutting off the water supply and disconnecting electrical power in the installation area.
2. Position the Appliance:
Carefully move the appliance into position. Use a level to ensure it is balanced correctly. An unlevel appliance can lead to operational issues and increased wear and tear. If balancing the appliance is challenging, MDTECH appliance installation services can assist.
3. Connect Water Supply:
For appliances that require water, such as dishwashers or washing machines, connect the water supply line. Apply Teflon tape to the threads to prevent leaks and tighten the connections securely.
4. Connect to Drainage:
Ensure that drainage hoses are properly connected and secure. Check for any kinks or bends in the hoses that might restrict water flow.
5. Plug In and Test:
Plug the appliance into the appropriate outlet. Turn the water supply back on and check for leaks. Run the appliance through a short cycle to ensure it operates correctly. For any unexpected issues, consult MDTECH appliance installation services.
Troubleshooting Common Issues
Even with careful planning, you might encounter some common issues during installation. Here's how to address them:
Leaks
1. Check Connections:
If you notice water leaks, double-check all connections. Ensure that hoses are tightly secured and that Teflon tape is applied correctly.
2. Inspect Hoses:
Inspect the hoses for any damage or wear. Replace any damaged hoses to prevent leaks.
Verify Power Source:
Ensure the appliance is properly plugged in and that the outlet is functioning. Use a multimeter to check for voltage.
3. Check Circuit Breaker:
If the appliance doesn’t turn on, check your home’s circuit breaker to ensure it hasn’t tripped. For persistent issues, MDTECH appliance installation services can diagnose and fix electrical problems.
Safety Tips for DIY Appliance Installation
Avoiding Injuries
1. Lift with Care:
When moving heavy appliances, use proper lifting techniques to avoid injuries. Enlist help if needed to avoid strain.
2. Use Proper Tools:
Always use the right tools for the job to avoid accidents and ensure a secure installation.
Frequently Asked Questions (FAQs)
What should I do if my appliance doesn't fit the designated space?

1,888,509 | Erectile Dysfunction Treatment in Dubai: Don't Let Cost Be a Barrier to Regaining Confidence? | Erectile dysfunction (ED) is a prevalent condition that affects a significant number of men... | 0 | 2024-06-14T11:47:14 | https://dev.to/dynamicclinicdubai/erectile-dysfunction-treatment-in-dubai-dont-let-cost-be-a-barrier-to-regaining-confidence-1n4d | Erectile dysfunction (ED) is a prevalent condition that affects a significant number of men worldwide, including those in Dubai. This condition, characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance, can have profound psychological and emotional impacts. The good news is that [Erectile Dysfunction Treatment In Dubai](https://www.dynamiclinic.com/en-ae/erectile-dysfunction-treatment-cost-in-dubai/), and modern medical advancements have made it possible for men to regain their confidence and lead fulfilling lives.
The Growing Need for Erectile Dysfunction Treatment in Dubai
Dubai, known for its advanced healthcare
infrastructure and world-class medical facilities, has become a hub for treating various health conditions, including erectile dysfunction. The cosmopolitan nature of the city attracts a diverse population, and the demand for high-quality, discreet, and effective ED treatments has been on the rise.
Comprehensive Erectile Dysfunction Treatment Options
1. Oral Medications
Oral medications are often the first line of treatment for ED. These include phosphodiesterase type 5 (PDE5) inhibitors such as Sildenafil (Viagra), Tadalafil (Cialis), and Vardenafil (Levitra). These medications work by increasing blood flow to the penis, helping to achieve and maintain an erection. They are typically effective and have relatively few side effects.
2. Injectable Treatments
For men who do not respond well to oral medications, injectable treatments can be an alternative. These involve injecting medication directly into the penis to induce an erection. Alprostadil, either alone or in combination with other medications, is commonly used for this purpose.
3. Vacuum Erection Devices
Vacuum erection devices (VEDs) are mechanical pumps that create a vacuum around the penis, drawing blood into it and causing an erection. A constriction band is then applied at the base of the penis to maintain the erection. VEDs are a non-invasive option and can be effective for many men.
4. Penile Implants
Penile implants are a surgical solution for erectile dysfunction. There are two main types of implants: inflatable and malleable. Inflatable implants allow for a more natural-looking erection, while malleable implants provide a permanent firmness. This option is usually considered when other treatments have failed.
5. Lifestyle Modifications and Natural Remedies
In addition to medical treatments, lifestyle modifications can play a crucial role in managing ED. This includes maintaining a healthy diet, regular exercise, quitting smoking, and reducing alcohol consumption. Natural remedies, such as herbal supplements and acupuncture, may also offer benefits, though their effectiveness can vary.
The Cost of Erectile Dysfunction Treatment in Dubai
1. Understanding the Costs Involved
The cost of ED treatments in Dubai can vary widely depending on the type of treatment chosen. Oral medications may cost between AED 50 to AED 500 per month, while injectable treatments can range from AED 200 to AED 1,000. Vacuum erection devices typically cost around AED 1,000 to AED 3,000. Penile implant surgery is the most expensive option, ranging from AED 30,000 to AED 70,000.
2. Insurance Coverage and Financing Options
Many insurance plans in Dubai cover some aspects of ED treatment, particularly if it is deemed medically necessary. It is essential to check with your insurance provider to understand what is covered. Additionally, financing options and payment plans are often available through clinics and hospitals, making these treatments more accessible.
3. The Value of Investing in Your Health
While the cost of ED treatment may seem high, it is important to consider the long-term benefits. Effective treatment can significantly improve quality of life, restore confidence, and enhance relationships. Investing in your health and well-being is invaluable and can have lasting positive effects.
Choosing the Right Erectile Dysfunction Clinic in Dubai
1. Research and Reviews
When selecting a clinic for ED treatment, thorough research is crucial. Look for clinics with positive reviews, testimonials from previous patients, and a solid reputation for providing high-quality care.
2. Expertise and Qualifications
Ensure that the clinic has qualified and experienced medical professionals who specialize in treating erectile dysfunction. The expertise of the healthcare providers can significantly impact the success of the treatment.
3. Personalized Treatment Plans
Every patient is unique, and the best clinics offer personalized treatment plans tailored to individual needs. This personalized approach ensures that you receive the most effective treatment for your specific condition.
Conclusion!
Erectile dysfunction is a treatable condition, and the array of options available in Dubai ensures that every man can find a solution that works for him. Whether through oral medications, injectable treatments, vacuum erection devices, penile implants, or lifestyle modifications, there is a path to regaining confidence and achieving a fulfilling life.
Do not let cost be a barrier to receiving the treatment you need. Explore the various options, understand the costs involved, and consider the value of investing in your health. With the right treatment, you can overcome erectile dysfunction and reclaim your confidence. | dynamicclinicdubai | |

1,888,503 | Case Study: Replacing Text | Suppose you are to write a program named ReplaceText that replaces all occurrences of a string in a... | 0 | 2024-06-14T11:38:36 | https://dev.to/paulike/case-study-replacing-text-f0p | java, programming, learning, beginners | Suppose you are to write a program named **ReplaceText** that replaces all occurrences of a string in a text file with a new string. The file name and strings are passed as command-line arguments as follows:
`java ReplaceText sourceFile targetFile oldString newString`
For example, invoking
`java ReplaceText FormatString.java t.txt StringBuilder StringBuffer`
replaces all the occurrences of **StringBuilder** by **StringBuffer** in the file **FormatString.java** and saves the new file in **t.txt**.
The program below gives the program. The program checks the number of arguments passed to the **main** method (lines 9–12), checks whether the source and target files exist (lines 15–26), creates a **Scanner** for the source file (line 30), creates a **PrintWriter** for the target file (line 31), and repeatedly reads a line from the source file (line 34), replaces the text (line 35), and writes a new line to the target file (line 36).
```
package demo;
import java.io.*;
import java.util.*;
public class ReplaceText {
public static void main(String[] args) throws Exception {
// Check command line parameter usage
if(args.length != 4) {
System.out.println("Usage: java ReplaceText sourceFile targetFile oldStr newStr");
System.exit(1);
}
// Check if source file exists
File sourceFile = new File(args[0]);
if(!sourceFile.exists()) {
System.out.println("Source file " + args[0] + " does not exist");
System.exit(2);
}
// Check if target file exists
File targetFile = new File(args[1]);
if(targetFile.exists()) {
System.out.println("Target file " + args[1] + " already exists");
System.exit(3);
}
try (
// Create input and output files
Scanner input = new Scanner(sourceFile);
PrintWriter output = new PrintWriter(targetFile);
){
while(input.hasNext()) {
String s1 = input.nextLine();
String s2 = s1.replaceAll(args[2], args[3]);
output.println(s2);
}
}
}
}
```
In a normal situation, the program is terminated after a file is copied. The program is terminated abnormally if the command-line arguments are not used properly (lines 9–12), if the source file does not exist (lines 15–19), or if the target file already exists (lines 23–26).

What are Document Conversion APIs?
These are APIs that can take a source input file in the form of docx, doc or PDF and convert them to PDF. As we have discussed before, converting to PDF has multiple pros, including consistent formatting, security and reduced file size.
In the blog post below, I wanted to show some of the available solutions out there: features, functionality, and benefits of each API.

1,409,027 | Kubernetes Health Checks | Kubernetes is an open-source container orchestration platform that helps manage and deploy... | 0 | 2023-03-21T11:03:41 | https://dev.to/roshanpnq/kubernetes-health-checks-34aa | devops, kubernetes |
Kubernetes is an open-source container orchestration platform that helps manage and deploy containerized applications. One of the critical features of Kubernetes is its ability to perform health checks on containers. Health checks allow Kubernetes to determine whether a container is running correctly and to take corrective action if necessary.
In this article, we will discuss the importance of health checks in Kubernetes and how they work.
### What are Health Checks in Kubernetes?
Health checks are a crucial feature of Kubernetes that help ensure the reliability of containerized applications. They enable Kubernetes to periodically check the health of containers and determine whether they are running correctly. A container may be running, but if it is not functioning as expected, it can cause issues for the application.
Kubernetes provides three types of health checks:
startup probe, liveness probe and readiness probe.
## Startup Probe
### Why do we need Startup Probe?
When a container starts up, it may take some time for the application inside the container to become fully operational. During this time, the container may be unresponsive or return error codes to incoming requests. This can cause issues for applications that require fast startup time or need to handle a large number of requests.
Startup probes let your containers inform Kubernetes when they’ve started up and are ready to be assessed for liveness and readiness.
_The kubelet uses startup probes to know when a container application has started. If such a probe is configured, it disables liveness and readiness checks until it succeeds, making sure those probes don’t interfere with the application startup._
### CONFIGURING A STARTUP PROBE:
Startup probe supports the four basic Kubernetes probing mechanism.
- Exec: Executes a command within the container. Probe succeeds if command exits with 0 status code.
- HTTP: Make HTTP call to a URL within a container. Probe succeeds if container issues HTTP response code 200–399 range.
- TCP: Probe succeeds if a specific container port is accepting traffic.
- gRPC: Makes a gRPC [health checking](https://github.com/grpc/grpc/blob/master/doc/health-checking.md) request to a port inside a container and uses its result to determine whether the probe succeeded.
All these mechanisms share some basic parameters that control the probe’s success criteria:
- initialDelaySeconds: Set a delay between the time the container starts and the first time the probe is executed. Defaults to zero seconds.
- periodSeconds: Defines how frequently the probe will be executed after the initial delay. Defaults to ten seconds.
- timeoutSeconds: Each probe will time out and be marked as failed after this many seconds. Defaults to one second.
- failureThreshold: Instructs Kubernetes to retry the probe this many times after a failure is first recorded. The container will only be restarted if the retries also fail. Defaults to three.
- Effective configuration of a startup probe relies on these values being set correctly.
## Readiness Probe
### Why do we need readiness probe?
A readiness probe is used to determine whether a container is ready to accept traffic. Kubernetes sends a request to the container, and if the container responds with a successful status code, it is considered ready. If the container fails to respond or responds with an error code, Kubernetes considers it not ready and stops sending traffic to the container.
Readiness probes are useful in preventing failed requests and ensuring that the application is only accessed when it is ready to serve traffic. If the application is not ready to serve traffic, the readiness probe prevents it from receiving requests thereby preventing users from accessing the application until its ready.
Configuration is same as the startup probe. For ex: Below yaml defines the readiness probe for a container.
```
`readinessProbe:
httpGet:
path: /healthz
port: 8080
initialDelaySeconds: 5
periodSeconds: 10`
```
## Liveness Probe
### Why do we need Liveness Probe?
A liveness probe is used to determine if a container is still alive. Kubernetes sends a request to the container, and if the container responds with a successful status code, it is considered alive. If the container fails to respond or responds with an error code, Kubernetes considers it as dead and restarts the container.
Liveness probes are useful in detecting application crashes, deadlocks, or other issues that cause the container to stop responding. By restarting the container automatically, Kubernetes ensures that the application remains available and responsive.
> Now, the biggest question is what should readiness and liveness probe actually check for?
The readiness probe checks if the application is ready to serve traffic, while the liveness probe checks if the application is still running and should be restarted if it’s not. Here are some guidelines on what these probes should check for:
Readiness Probe:
- Verify that the application has successfully started up and initialized all necessary components (e.g., databases, caches).
- Check that any required dependencies or connections (e.g., databases, APIs) are available and responsive.
- Confirm that any configuration files or environment variables have been loaded correctly.
- Validate that the application is able to handle incoming requests and respond appropriately
Liveness Probe:
- Check that the application process is running throughout the lifecycle of the pod.
- Test that the application is able to perform its intended function (e.g., processing requests, writing to a database) within a certain time limit.
- Check for any stuck or deadlocked threads in the application.
- Test that the application is not consuming too much memory or CPU resources, which could cause it to crash.
By setting up appropriate readiness and liveness probes, you can detect and handle problems with your Kubernetes applications even before they impact your users. | roshanpnq |

In this article I'll focus on how to efficiently **structure the logic in the HTTP request stream pipelines** for the loading and saving of the user data. Currently, the entire logic is handled within the `UserProfileComponent` class. I'll refactor this to achieve a more declarative and reusable approach.
_**A quick note**:_
- _Before we begin, please note that this article builds on concepts and code introduced in previous articles of this series. If you're new here, I highly recommend that you check out those articles first to get up to speed._
- _The starting point for the code I'll be working with in this article can be found in the `14.image-form-control` branch of the repository https://github.com/cezar-plescan/user-profile-editor/tree/14.image-form-control._
#### In this article I'll guide you through:
- How to break down complex logic into smaller, reusable RxJS operators.
- The role of the `catchError` operator in error handling.
- Strategies for handling validation errors, upload progress, and successful responses within observable pipelines.
- The benefits of using custom operators for cleaner, more maintainable code.
- How to create custom operators like `tapValidationErrors`, `tapUploadProgress`, `tapResponseBody`, and `tapError` to make the code more streamlined and easier to manage.
By the end of this article, you'll have a deeper understanding of how to leverage custom RxJS operators to manage the intricacies of HTTP requests and responses in your Angular applications.
## Identifying the current issues
The code of the `saveUserData()` method of the `UserProfileComponent` class in the [user-profile.component.ts](https://github.com/cezar-plescan/user-profile-editor/blob/14.image-form-control/src/app/user-profile/user-profile.component.ts#L141-L186) file looks like this:{% embed https://gist.github.com/cezar-plescan/0ec6e15d4a7556cb584c653c7fb5cabd %}
The method is quite lengthy and handles multiple tasks, such as detecting response error types and computing upload progress. This violates the Single Responsibility Principle, making the code less maintainable. Ideally, the component should only be concerned with receiving errors, user data, and upload progress, not the intricacies of error handling or progress calculation.
To address all these, I'll create custom RxJS operators to handle different aspects of the HTTP request stream. This approach will lead to a more declarative and reusable code structure.
I'll start by implementing an operator for validation error handling, which I'll name `tapValidationErrors`.
## Handling validation errors: the `tapValidationErrors` operator
The core idea behind this operator is to apply the **extract method** refactoring technique. I'll move the validation error handling code from the component into a separate, reusable function that can be used in the observable pipe chain.
The reason behind naming this operator is that the _tap_ prefix aligns with the RxJS convention of using it for operators that perform side effects (like logging or triggering actions) without modifying the values in the stream. While this operator doesn't directly modify values, it does perform the side effect of invoking the callback function for validation errors.
### Benefits of this approach
- **Separation of concerns**: The error handling logic is decoupled from the main subscription logic, improving code organization and readability.
- **Reusability**: The operator can be easily reused across different observables and components that need to handle validation errors in a similar way, promoting a DRY (Don't Repeat Yourself) approach.
- **Flexibility**: The operator provides a clear way to customize the error handling behavior for validation errors without affecting the handling of other types of errors.
### Implementation and usage
Let's create a new file, `tap-validation-errors.ts`, in the `src/app/shared/rxjs-operators` folder with the following content:{% embed https://gist.github.com/cezar-plescan/d1b27d6f733d8080ce442581dd1b43f0 %}I've also updated the `saveUserData()` method in the `user-profile.component.ts` file:{% embed https://gist.github.com/cezar-plescan/2f15d364ca670f916ea0e980c0f16593 %}
Let's break down what I've done here. I'll first examine the method in the component.
### Simplifying the `saveUserData()` method
The `catchError` operator is now responsible for only handling global errors.
I've introduced the new operator `tapValidationErrors` before it. This order is crucial, as placing `catchError` before `tapValidationErrors` would cause it to catch and handle all errors, including validation errors, preventing `tapValidationErrors` from specifically addressing those validation errors. By placing `tapValidationErrors` first, I ensure that validation errors are identified and processed _before_ any other error handling logic.
### How the operator works
Now let's talk about the logic inside the `tapValidationErrors` operator.
After extracting the validation error handling code from the `catchError` block from the `saveUserData()` method, I could have simply used two separate `catchError` operators in the pipeline: one dedicated to validation errors and the other for general errors. While this would separate the logic, it wouldn't necessarily improve reusability or code organization.{% embed https://gist.github.com/cezar-plescan/0c3ffe86487b49467bc764874c634fe2 %}
Instead, I can adopt a more elegant solution by encapsulating the extracted logic into a reusable custom operator. This leverages the power of RxJS operator composition, where we can combine existing operators to create new ones with specialized behavior.
In this case, the `tapValidationErrors` operator is essentially a higher-order function that takes a callback function as an argument and returns a new RxJS operator based on `catchError`. This custom operator handles validation errors in a controlled and informative manner, allowing us to perform specific actions like displaying error messages while leaving other error types to be handled elsewhere in the pipeline.
The `callback` parameter in the operator definition will be invoked when these errors are detected. In the component method `saveUserData()` I specify the exact action to take when validation errors are received from the server, which in this instance is to display the errors in the form.
#### Error handling strategies in `catchError`
There's one crucial aspect in the implementation I want to discuss: the use of `return EMPTY` and `throw error`. The `catchError` operator requires that its inner callback either returns an observable or throws an exception.
By returning `EMPTY`, I explicitly indicate that this error in the stream has been handled within this operator. This prevents the error from propagating further down the observable chain and triggering another error handler, which is not what I expect to happen. `EMPTY` is a special observable that immediately completes without emitting any values. By returning this observable, we effectively terminate the current observable stream. This is important because, in the context of a form submission, we don't want to continue processing the response if the server indicates validation errors.
On the other hand, by using `throw error`, I'm explicitly re-throwing errors that are not validation errors. This allows these errors to be caught and handled by a higher-level `catchError` operator in our RxJS pipeline or by a global error handler in the application (like the `ErrorHandler` injection token or an HTTP interceptor).
## Tracking upload progress: the `tapUploadProgress` operator
I'll continue to refine the file upload handling by addressing the calculation of upload progress. Currently, this logic resides in the observer in the `saveUserData()` method, which, as I discussed earlier, isn't ideal. My goal is to create a separate operator that handles this task exclusively. Building upon the approach I've taken with the `tapValidationErrors` operator, I'll create a new file `tap-upload-progress.ts` in the same folder. I'll name the operator `tapUploadProgress`. Here is the content of the file:{% embed https://gist.github.com/cezar-plescan/51ebcbfe438df2e635bec186a02ab2d6 %}I've removed the extracted code from the `saveUserData()` method, and added the new operator:{% embed https://gist.github.com/cezar-plescan/a0b716b9162844bbf10825bdc886bf5a %}
By extracting the progress calculation into the `tapUploadProgress` operator, I've decluttered the `saveUserData()` method and made it more focused on its core responsibilities. This enhances code readability and maintainability while promoting reusability of the progress-tracking logic across other parts of our application.
### Configuring upload progress tracking
In order to access upload progress information, we need to configure the HTTP request with two specific options: `reportProgress: true` and `observe: 'events'`: {% embed https://gist.github.com/cezar-plescan/e17e9f9fb6738912957e8dd016a76066 %}
In `HttpClient`, methods like `put`, `post`, `get`, etc., accept an optional third argument called `options`. This argument is an object that allows us to configure various aspects of the HTTP request and how the response is handled.
With both `reportProgress: true` and `observe: 'events'`, we get an observable that emits a stream of `HttpEvent` objects. Each event represents a different stage of the HTTP request/response lifecycle.
#### `reportProgress: true`
This option tells `HttpClient` to track the progress of the HTTP request, particularly relevant for uploads and downloads.
When `reportProgress` is true, `HttpClient` emits `HttpEventType.UploadProgress` (for uploads) or `HttpEventType.DownloadProgress` (for downloads) events as part of the observable stream. These events contain information about the progress, such as loaded bytes and total bytes.
In the context of our image upload component, this allows us to track the upload progress and provide feedback to the user through the progress bar indicator.
_**Note**: Even without this option, the code will still work fine, but we'll have no progress indicator. The `if` condition in the `tapUploadProgress` operator won't be satisfied, and the callback for updating the progress won't be invoked._
#### `observe: 'events'`
This option instructs `HttpClient` to emit the full sequence of HTTP events instead of just the final response body.
The emitted events can include:
- `HttpEventType.Sent`: The request has been sent to the server.
- `HttpEventType.UploadProgress` (for uploads): Provides progress information.
- `HttpEventType.Response`: The response has been received from the server (this contains the data we usually work with).
By observing events, we gain access to more granular information about the HTTP request lifecycle. In our case, we're using it to access the UploadProgress events to track progress and the Response event to get the final server response.
## Extracting the response body with the `tapResponseBody` operator
Let's make our code even better by introducing another handy tool: the `tapResponseBody` operator. This operator helps us grab the data we want from successful responses to our HTTP requests.
### The code
Here is the content of the `tap-response-body.ts` file: {% embed https://gist.github.com/cezar-plescan/334325ce612a2488d6388e5162ecd4d6 %}And the updated `saveUserData()` method: {% embed https://gist.github.com/cezar-plescan/4c3237e18b9a10462b23f0fbab34b9f3 %}
### Why Use `tapResponseBody`?
Right now, the `saveUserData` method handles successful responses directly inside the `subscribe` block. This works, but it can get messy as our form gets more complex. The `tapResponseBody` operator cleans things up by separating this logic into a reusable piece.
With `tapResponseBody`, we can:
- Separate response handling: Keep the code that deals with the response data away from the main part of the `saveUserData` method. This makes our code tidier and easier to read.
- Reuse the logic: Use the same response handling code for other parts of our app where we need to get data from successful responses.
- Focus on the big picture: Keep the `subscribe` part simple and focused on the main actions, while the `tapResponseBody` operator handles the fine details of dealing with the response.
### Updating the `loadUserData()` method
Now that we've successfully applied the `tapResponseBody` operator for the `saveUserData()` method, let's see how we can apply it for the `loadUserData()` method. I'll take a similar approach and move the code from the `subscribe` method into our operator inner callback:{% embed https://gist.github.com/cezar-plescan/40b72f576610b4ca5bfe7bae1f283718 %}However, when compiling it, we get a few TypeScript errors:{% embed https://gist.github.com/cezar-plescan/f1db6e2ea9b9812a5c127841cfee1305 %}
#### Understanding the challenge
Why doesn't this work smoothly? The problem lies in how our HTTP requests are set up. Let's take a closer look at the two methods:{% embed https://gist.github.com/cezar-plescan/afe9ced99e8a87b6fb2e04d4a0e3d7e7 %}There is a key difference. The save request uses `observe: 'events'`, meaning it gives a stream of `HttpEvent<UserDataResponse>` objects. But `getUserData$()` doesn't speficy this option, so it defaults to `observe: 'body'`, which gives us the response data directly. Notice the `map` operator which receives values of type `UserDataResponse`, but it converts them to `UserProfile`.
Our `tapResponseBody` operator is designed to work with `HttpEvent` objects. This mismatch is causing these TypeScript errors.
At a high level, I see primarily two ways to address this issue:
1. to modify **`getUserData$()`**, or,
2. to adapt the **`tapResponseBody`** operator.
#### Modify the `getUserData$()` stream
I could change the GET request to also use `observe: 'events'`, just like `saveUserData$()`. This would make both requests consistent, and `tapResponseBody` would work as is. However, this would also make our operator less flexible; it would only work with observables that emit `HttpEvent` objects.
Here is how this solution could be implemented:{% embed https://gist.github.com/cezar-plescan/9722e85606743fd641650da381219930 %}
This might be simpler if we only have a few places where we need to handle both `HttpEvent` and response body types. On the other hand, we might need to repeat code if we use this pattern in multiple places, and the `tapResponseBody` operator would be less reusable.
#### Adapt the `tapResponseBody` operator
This solution implies the operator to work with requests no matter the value of the `observe` option, which could be one of: `"body", "response", "events"`. This would make the operator more versatile and adaptable to different HTTP request configurations. It also offers more flexibility and reusability, especially if we have multiple observables that emit either event or response body types. It also encapsulates the type-handling logic within the operator itself. Of course, the tradeoff is that it requires more development work for adapting the logic inside the operator.
I'll choose the more flexible route and enhance the operator to handle both scenarios. For improved clarity, I'll rename it to `tapResponseData`. Here's the updated code:{% embed https://gist.github.com/cezar-plescan/99aebd9da3ab3ffe32f1d5700524f706 %}Take a moment to read the comments in the code – they explain how I've improved the operator to handle different types of responses.
The generic type `<T>` in the operator now represents the specific type of data we expect from the response, `UserDataResponse`.
Additionally, I've created new files with different data types and interfaces:{% embed https://gist.github.com/cezar-plescan/cc6865dee1fc6b92fd9356293053c198 %}
Here is the updated component where the operator is used:{% embed https://gist.github.com/cezar-plescan/ca46bdac3d9f00d8e75f9368c1a5ad56 %}
Since `tapResponseData` now handles different kinds of responses, the other two operators `tapValidationErrors` and `tapUploadProgress` need to be updated too. The fix is to specify the new type `HttpClientResponse<T>`, instead of the old one`HttpEvent<T>`, which was available only when the `observe` option was set to `'events'`. Here are their updated code:{% embed https://gist.github.com/cezar-plescan/0bf6c70ef8bc287243e2e6e568b0eec8 %}
You can test the code with different settings for the `observe` option in both load and save requests. The code should successfully handle all scenarios.
## Error handling made easy: the `tapError` operator
To improve the error handling and make the code more compact, I'll introduce a new custom RxJS operator called `tapError`. This operator will serve as a dedicated mechanism for handling errors in HTTP request streams, like replacing the `catchError` block in the `loadUserData()` or `saveUserData()` methods.
### The purpose of `tapError`
The primary goal of the `tapError` operator is to execute specific actions when an error occurs within an observable stream. In our case, the `loadUserData()` method needs to be notified when an HTTP error happens so we can set an error flag in the UI.
### Implementation
Here's the implementation of the operator:{% embed https://gist.github.com/cezar-plescan/4b60e98cdd205634c706b4ea852475bc %}The usage in the component is straightforward:{% embed https://gist.github.com/cezar-plescan/15ebfa7d08053bb14dbbf765c676cb96 %}
One important distinction: the `tapError` operator is designed for single use within a stream. Why? Because the stream will terminate immediately after the operator handles the error.
### Error handling strategies in RxJS
There are several ways to respond to errors in RxJS streams:
- `catchError` operator: this is the most common and flexible way to handle errors. It allows us to catch errors and decide how to proceed, either by returning a new observable, emitting a fallback value, or throwing the error again.
- `tap` operator with `error` callback: executes a side effect when an error occurs but allows the error to propagate further.
- `subscribe` method's `error` callback: Handles the error at the end of the observable chain.
### Why `catchError` is the right tool
Here is an alternative implementation of the `tapError` with the `tap` operator and the `error` callback: {% embed https://gist.github.com/cezar-plescan/7a37dd1cd873535c6f53542f904ffa5f %}If you use this implementation, the behavior of the `loadUserData()` would remain the same.
In our scenario, I'm interested in both handling the error (setting the `hasLoadingError` flag) and stopping the error from propagating. This aligns perfectly with the purpose of `catchError`. Here's why `tap` with the `error` callback wouldn't be ideal:
- uncontrolled error propagation: The `tap` operator doesn't stop errors from continuing down the stream. This means the error would still reach the `subscribe` block `error` callback, potentially causing duplicate error handling and unexpected behavior.
- limited control: While `tap` allows us to perform actions in response to errors, it doesn't let us change the stream's behavior fundamentally. In our case, we want to stop the stream after an error, which `tap` can't do.
By using `catchError` with `return EMPTY`, we achieve clear error handling and explicit stream termination.
## Conclusion: A cleaner, more maintainable approach
In this article, I've shown you how custom RxJS operators can make the Angular code much cleaner and easier to work with. I created special operators like `tapValidationErrors`, `tapUploadProgress`, `tapResponseData` and `tapError` to handle different parts of HTTP requests.
By using these custom operators, we've made our code:
- easier to understand - each operator does one specific job, making it simpler to read and follow the logic.
- reusable - we can use these operators in other parts of the project, saving us time and effort.
- more flexible - we can now easily change how we handle errors or responses without affecting other parts of the code.
Feel free to explore and experiment with the code from this article, available in the `15.http-rxjs-operators` branch of the repository: https://github.com/cezar-plescan/user-profile-editor/tree/15.http-rxjs-operators.
I hope this article helps you see how awesome custom RxJS operators are. Feel free to use these ideas in your own Angular projects and let me know if you have any questions or comments. Let's keep learning and improving together as Angular developers.

İşte bazı nedenler:
Boyut Uyumu: Birçok derin öğrenme modeli, giriş olarak sabit boyutlarda görüntüler gerektirir. Bu nedenle, veri kümenizdeki tüm görüntülerin aynı boyutta olması önemlidir. Yeniden boyutlandırma, farklı boyutlardaki görüntüleri istenen sabit boyuta getirmek için kullanılır.
Hesaplama Verimliliği: Büyük boyutlardaki görüntülerin işlenmesi, daha fazla hesaplama gücü ve bellek gerektirir. Görüntüleri daha küçük boyutlara yeniden boyutlandırmak, hesaplama verimliliğini artırabilir ve modelin daha hızlı çalışmasını sağlayabilir.
Overfitting Önleme: Büyük boyutlardaki görüntüler, modelin ezberlemesine (overfitting) yol açabilir, özellikle de veri setiniz sınırlıysa. Yeniden boyutlandırma, gereksiz ayrıntıları azaltarak ve verinin genelleştirilebilirliğini artırarak overfitting'i azaltabilir.
Görüntü Kalitesi: Bazı durumlarda, orijinal görüntüler yüksek çözünürlüklü olabilir ve bu da gereksiz detaylarla dolu olabilir. Yeniden boyutlandırma, gereksiz detayları azaltarak ve görüntüyü daha işlenebilir hale getirerek işleme sürecini kolaylaştırabilir.
Veri Ön İşleme: Görüntü işleme uygulamalarında, veri önceden işlenir ve modele sunulur. Yeniden boyutlandırma, veri ön işleme adımının önemli bir parçasıdır ve genellikle görüntülerin modelin işlemesi için uygun hale getirilmesini sağlar.
Bu nedenlerle, görüntü boyutlarının yeniden boyutlandırılması, veri hazırlığı sürecinin önemli bir parçasıdır ve modelin verimli ve etkili bir şekilde çalışmasını sağlar. | mustafacam | |

This feature is useful in scenarios where you want to handle variable-length iterables or where specific elements need to be extracted from a larger sequence without explicitly indexing each element.
Real-World Use Case Scenario:
Let's consider a practical example to illustrate the usefulness of extended unpacking:
Use Case: Processing Multiple Return Values from a Function
Imagine you have a function that returns multiple values, but you are interested in only a few specific values and want to discard the rest. Extended unpacking makes it straightforward to handle this scenario.
```
# Function that returns multiple values
def get_statistics(data):
mean = sum(data) / len(data)
median = sorted(data)[len(data) // 2]
mode = max(set(data), key=data.count)
return mean, median, mode, min(data), max(data)
# Example usage of the function
data = [10, 20, 10, 30, 40, 50, 20, 10]
mean, median, *_, maximum_value = get_statistics(data)
print("Mean:", mean)
print("Median:", median)
print("Maximum Value:", maximum_value)
```
Explanation:
Function get_statistics:
Computes several statistical measures (mean, median, mode, min, max) based on the input data.
Extended Unpacking in Action:
mean, median, *_, maximum_value = get_statistics(data)
mean, median, and maximum_value are directly assigned the first, second, and last values returned by get_statistics(data) respectively.
*_, collects and discards any additional return values (mode, min(data)) into a list _. This is indicated by the * operator followed by a throwaway variable _.
Printing the Results:
```
print("Mean:", mean): Prints the calculated mean.
print("Median:", median): Prints the calculated median.
print("Maximum Value:", maximum_value): Prints the maximum value from the input data.
```
Advantages of Extended Unpacking:
Concise and Readable Code: It simplifies code by handling multiple return values succinctly.
Efficient Data Extraction: Allows selective extraction of required values while discarding others.
Flexibility: Handles variable-length data structures without explicitly indexing each element.
Conclusion:
Python's extended unpacking feature (* operator) enhances code clarity and flexibility, particularly in scenarios involving functions with multiple return values or operations on variable-length iterables. It's a powerful tool for managing and extracting data efficiently in real-world programming tasks. | jeevanizm |

A **File** object encapsulates the properties of a file or a path, but it does not contain the methods for creating a file or for writing/reading data to/from a file (referred to as data _input_ and _output_, or _I/O_ for short). In order to perform I/O, you need to create objects using appropriate Java I/O classes. The objects contain the methods for reading/writing data from/to a file. There are two types of files: text and binary. Text files are essentially characters on disk. This section introduces how to read/write strings and numeric values from/to a text file using the Scanner and PrintWriter classes.
## Writing Data Using PrintWriter
The **java.io.PrintWriter** class can be used to create a file and write data to a text file. First, you have to create a **PrintWriter** object for a text file as follows:
`PrintWriter output = new PrintWriter(filename);`
Then, you can invoke the **print**, **println**, and **printf** methods on the **PrintWriter** object to write data to a file. Figure below summarizes frequently used methods in **PrintWriter**.
The program below gives an example that creates an instance of **PrintWriter** and writes two lines to the file **scores.txt**. Each line consists of a first name (a string), a middle-name initial (a character), a last name (a string), and a score (an integer).
Lines 8–11 check whether the file scores.txt exists. If so, exit the program (line 10).
Invoking the constructor of **PrintWriter** will create a new file if the file does not exist. If the file already exists, the current content in the file will be discarded without verifying with the user.
Invoking the constructor of **PrintWriter** may throw an I/O exception. Java forces you to write the code to deal with this type of exception. For simplicity, we declare **throws IOException** in the main method header (line 6).
You have used the **System.out.print**, **System.out.println**, and **System.out.printf** methods to write text to the console. **System.out** is a standard Java object for the console output. You can create **PrintWriter** objects for writing text to any file using **print**, **println**, and **printf** (lines 17–20).
The **close()** method must be used to close the file (line 23). If this method is not invoked, the data may not be saved properly in the file.
## Closing Resources Automatically Using try-with-resources
Programmers often forget to close the file. The followings new try-with-resources syntax automatically closes the files.
`try (declare and create resources) {
Use the resource to process the file;
}`
Using the try-with-resources syntax, we rewrite the code in the program above, WriteData.java, in the program below.
A resource is declared and created followed by the keyword **try**. Note that the resources are enclosed in the parentheses (lines 12–15). The resources must be a subtype of **AutoCloseable** such as a **PrinterWriter** that has the **close()** method. A resource must be declared and created in the same statement and multiple resources can be declared and created inside the parentheses. The statements in the block (lines 15–21) immediately following the resource declaration use the resource. After the block is finished, the resource’s **close()** method is automatically invoked to close the resource. Using try-with-resources can not only avoid errors but also make the code simpler.
## Reading Data Using Scanner
A **Scanner** breaks its input into tokens delimited by whitespace characters. To read from the keyboard, you create a **Scanner** for System.in, as follows:
`Scanner input = new Scanner(System.in);`
To read from a file, create a **Scanner** for a file, as follows:
`Scanner input = new Scanner(new File(filename));`
Figure below summarizes frequently used methods in **Scanner**.
The program below gives an example that creates an instance of **Scanner** and reads data from the file **scores.txt**.
Note that **new Scanner(String)** creates a **Scanner** for a given string. To create a **Scanner** to read data from a file, you have to use the **java.io.File** class to create an instance of the **File** using the constructor **new File(filename)** (line 8), and use **new Scanner(File)** to create a **Scanner** for the file (line 11).
Invoking the constructor **new Scanner(File)** may throw an I/O exception, so the **main** method declares **throws Exception** in line 6.
Each iteration in the **while** loop reads the first name, middle initial, last name, and score from the text file (lines 14–20). The file is closed in line 23.
It is not necessary to close the input file (line 23), but it is a good practice to do so to release the resources occupied by the file. You can rewrite this program using the try-with-resources syntax.
## How Does **Scanner** Work?
The **nextByte()**, **nextShort()**, **nextInt()**, **nextLong()**, **nextFloat()**, **nextDouble()**, and **next()** methods are known as _token-reading methods_, because they read tokens separated by delimiters. By default, the delimiters are whitespace characters. You can use the **useDelimiter(String regex)** method to set a new pattern for delimiters.
How does an input method work? A token-reading method first skips any delimiters (whitespace characters by default), then reads a token ending at a delimiter. The token is then automatically converted into a value of the **byte**, **short**, **int**, **long**, **float**, or **double** type for **nextByte()**, **nextShort()**, **nextInt()**, **nextLong()**, **nextFloat()**, and **nextDouble()**, respectively. For the **next()** method, no conversion is performed. If the token does not match the expected type, a runtime exception **java.util.InputMismatchException** will be thrown.
Both methods **next()** and **nextLine()** read a string. The **next()** method reads a string delimited by delimiters, and **nextLine()** reads a line ending with a line separator.
The line-separator string is defined by the system. It is **\r\n** on Windows and **\n** on UNIX. To get the line separator on a particular platform, use
`String lineSeparator = System.getProperty("line.separator");`
If you enter input from a keyboard, a line ends with the _Enter_ key, which corresponds to the **\n** character.
The token-reading method does not read the delimiter after the token. If the **nextLine()** method is invoked after a token-reading method, this method reads characters that start from this delimiter and end with the line separator. The line separator is read, but it is not part of the
string returned by **nextLine()**.
Suppose a text file named **test.txt** contains a line
`34 567`
After the following code is executed,
`Scanner input = new Scanner(new File("test.txt"));
int intValue = input.nextInt();
String line = input.nextLine();`
**intValue** contains **34** and **line** contains the characters **' '**, **5**, **6**, and **7**.
What happens if the input is _entered from the keyboard_? Suppose you enter **34**, press the _Enter_ key, then enter **567** and press the _Enter_ key for the following code:
`Scanner input = new Scanner(System.in);
int intValue = input.nextInt();
String line = input.nextLine();`
You will get **34** in **intValue** and an empty string in **line**. Why? Here is the reason. The token-reading method **nextInt()** reads in **34** and stops at the delimiter, which in this case is a line separator (the _Enter_ key). The **nextLine()** method ends after reading the line separator and returns the string read before the line separator. Since there are no characters before the line separator, **line** is empty.
You can read data from a file or from the keyboard using the **Scanner** class. You can also scan data from a string using the **Scanner** class. For example, the following code
`Scanner input = new Scanner("13 14");
int sum = input.nextInt() + input.nextInt();
System.out.println("Sum is " + sum);`
displays
`The sum is 27` | paulike |

JavaScript classes, introduced in ECMAScript 2015 (ES6), provide a much cleaner and more intuitive syntax for creating objects and dealing with inheritance. This post explores JavaScript classes in depth, covering essential concepts and features with clear examples.
---
### 1. **Overview**
JavaScript classes are templates for creating objects. They encapsulate data with code to work on that data. Although they are primarily syntactical sugar over JavaScript's existing prototype-based inheritance, classes make object-oriented programming more accessible and easier to understand.
**Example:**
```javascript
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
}
}
const person1 = new Person('Alice', 30);
person1.greet(); // Hello, my name is Alice and I am 30 years old.
```
---
### 2. **Constructor**
The `constructor` method is a special method for creating and initializing an object created with a class. There can be only one special method with the name "constructor" in a class.
**Example:**
```javascript
class Car {
constructor(brand, model) {
this.brand = brand;
this.model = model;
}
displayInfo() {
console.log(`This car is a ${this.brand} ${this.model}.`);
}
}
const myCar = new Car('Toyota', 'Corolla');
myCar.displayInfo(); // This car is a Toyota Corolla.
```
---
### 3. **Extends**
The `extends` keyword is used in class declarations or class expressions to create a class that is a child of another class.
**Example:**
```javascript
class Animal {
constructor(name) {
this.name = name;
}
speak() {
console.log(`${this.name} makes a noise.`);
}
}
class Dog extends Animal {
speak() {
console.log(`${this.name} barks.`);
}
}
const myDog = new Dog('Rex');
myDog.speak(); // Rex barks.
```
---
### 4. **Private Properties**
Private properties are declared with a `#` prefix, making them inaccessible from outside the class.
**Example:**
```javascript
class User {
#password;
constructor(username, password) {
this.username = username;
this.#password = password;
}
checkPassword(password) {
return this.#password === password;
}
}
const user1 = new User('john_doe', '12345');
console.log(user1.checkPassword('12345')); // true
console.log(user1.#password); // SyntaxError: Private field '#password' must be declared in an enclosing class
```
---
### 5. **Public Class Fields**
Public class fields are properties that can be defined directly within the class body, making them more concise and readable.
**Example:**
```javascript
class Product {
name = 'Default';
price = 0;
constructor(name, price) {
this.name = name;
this.price = price;
}
displayProduct() {
console.log(`Product: ${this.name}, Price: $${this.price}`);
}
}
const product1 = new Product('Laptop', 1200);
product1.displayProduct(); // Product: Laptop, Price: $1200
```
---
### 6. **Static Methods**
Static methods are called on the class itself, not on instances of the class. They are often used to create utility functions.
**Example:**
```javascript
class MathUtils {
static add(a, b) {
return a + b;
}
static subtract(a, b) {
return a - b;
}
}
console.log(MathUtils.add(5, 3)); // 8
console.log(MathUtils.subtract(5, 3)); // 2
```
---
### 7. **Static Initialization Blocks**
Static initialization blocks allow you to perform complex initialization of static properties.
**Example:**
```javascript
class Config {
static API_URL;
static PORT;
static {
this.API_URL = 'https://api.example.com';
this.PORT = 8080;
}
static getConfig() {
return `API URL: ${this.API_URL}, PORT: ${this.PORT}`;
}
}
console.log(Config.getConfig()); // API URL: https://api.example.com, PORT: 8080
```
---
### 8. **Getters and Setters**
Getters and setters are used to define methods that get and set the value of an object’s properties.
**Example:**
```javascript
class Person {
constructor(firstName, lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
get fullName() {
return `${this.firstName} ${this.lastName}`;
}
set fullName(name) {
[this.firstName, this.lastName] = name.split(' ');
}
}
const person = new Person('John', 'Doe');
console.log(person.fullName); // John Doe
person.fullName = 'Jane Smith';
console.log(person.fullName); // Jane Smith
```
---
### 9. **Instance Methods**
Instance methods are methods defined within a class that operate on instances of that class.
**Example:**
```javascript
class Rectangle {
constructor(width, height) {
this.width = width;
this.height = height;
}
area() {
return this.width * this.height;
}
perimeter() {
return 2 * (this.width + this.height);
}
}
const rectangle = new Rectangle(10, 5);
console.log(rectangle.area()); // 50
console.log(rectangle.perimeter()); // 30
```
---
### Conclusion
JavaScript classes offer a clean and concise way to create and manage objects, providing a range of features to support object-oriented programming. By understanding constructors, inheritance, private properties, public fields, static methods, and other concepts, you can leverage the full power of JavaScript classes in your projects. Happy coding!

Workday’s Enterprise Management Cloud is revolutionizing business operations with its comprehensive suite of tools for financial management, enterprise resource planning (ERP), and human capital management (HCM). As of 2024, Workday’s management cloud continues to dominate the market, with over 10,000 organizations worldwide, including more than 50% of the Fortune 500 companies turning to its innovative solutions. Beyond mere streamlining of operations, it presents automation validation solutions, augmenting both efficiency and precision. This article explores how Workday’s platform is reshaping the businesses globally, providing insights into the future of enterprise management and Workday testing automation.
**Understanding Workday’s Enterprise Management Cloud**
The Management Cloud offered by Workday stands as a suite of applications meticulously crafted to centralize and refine fundamental business operations. It provides a cohesive platform tailored to oversee vital HR, finance, and planning functions.
**Key Features and Capabilities**:
**Centralized Data**: Workday harmonizes data from assorted departments, such as HR and finance, into a solitary reservoir, abolishing data compartmentalization and ensuring uniformity.
**Streamlined Procedures**: Automated protocols simplify endeavors such as orienting new personnel, managing payroll, and formulating financial summaries.
**Enhanced Insight**: Real-time dashboards furnish enlightenment on pivotal performance metrics throughout the enterprise, facilitating data-grounded decision-making.
**Scalability and Adaptability**: The cloud-centric framework adjusts to the expansion of enterprises and seamlessly integrates with preexisting systems.
Through the centralization of data and automation of tasks, Workday rationalizes workflows, augments operational effectiveness, and diminishes manual fallacies. This results in expedited turnaround times, superior resource allotment, and, ultimately, heightened business dexterity.
**How Workday is Streamlining Business Operations**?
Workday streamlines business operations by automating and simplifying processes, such as budgeting, planning, and forecasting. This reduces the need for manual intervention, which saves time and resources and allows organizations to focus on strategic initiatives.
Workday also offers a consolidated platform that integrates financial management, ERP, and HCM, eliminating data silos and ensuring that all departments work harmoniously. This leads to improved decision-making and streamlined processes.

This solution helps companies oversee employee operations and gain greater visibility into the entire workforce.
Workday’s Financial Management helps streamline financial operations by providing modern management capabilities in an adaptive cloud-based solution and supporting transaction processing, multidimensional reporting, consolidation, planning, and compliance.
**The Role of Automation in Business Efficiency**
Workday’s cloud-based platform offers a robust system for managing your core business functions. But maximizing its efficiency requires streamlining workflows. Automation tackles repetitive tasks, saving valuable time for your team. Imagine payroll processing running flawlessly, or expense reports receiving automatic approvals. This frees employees to focus on strategic initiatives and exceptional customer service.
Different Roles of Automation in Business:
**Improved Accuracy**: Reduce human error in manual tasks.
**Enhanced Productivity**: Free up employees for higher-value activities.
**Faster Workflows**: Streamline approvals and communication for quicker turnaround times.
**Cost Reduction**: Save resources by automating tasks previously requiring manual effort.

1,888,486 | HIGHER ORDER ARRAY METHODS IN JAVASCRIPT | WHAT ARE HIGHER ORDER METHODS? Higher order array methods in javascript are built-in methods that... | 0 | 2024-06-14T11:23:50 | https://dev.to/shreeprabha_bhat/higher-order-array-methods-in-javascript-4hjl | **WHAT ARE HIGHER ORDER METHODS?**
Higher order array methods in javascript are built-in methods that take a function as an argument or return a function as a result.
In Javascript we use many higher order methods that helps in several array manipulation tasks. Few of commonly used array methods are:
1. forEach()
2. map()
3. filter()
4. reduce()
5. find()
6. findIndex()
7. some()
8. every()
9. sort()
10. flatmap()
In this blog I am going to discuss about the most commonly asked higher order methods that are **map()**, **reduce()** and **filter()**.
**map()**
map() higher order method is used to map through an array and return a new array by performing some operation.
Syntax
```
map((value)=>{
})
map((value,index)=>{
})
map((value,index,array)=>{
})
```
Example
```
let a=[1,2,3,4]
let a1=a.map((value)=>{
console.log(value)
return value+2
})
let a2=a.map((value,index)=>{
console.log(value,index)
return value+2
})
let a3=a.map((value,index,array)=>{
console.log(value,index,array)
return value+2
})
```
**filter()**
filter() method is used to filter an array with values that passes the test.
Syntax
```
filter((value)=>{
})
filter((value,index)=>{
})
filter((value,index,array)=>{
})
```
Example
```
let a=[28,96,15,1,3,5]
let a1=a.filter((value)=>{
return value>10
})
console.log(a1)
```
**reduce()**
reduce() method is used to reduce an array into a single value. reduce() method usually takes two parameters as an argument.
Syntax
```
reduce((h1,h2)=>{
})
```
Example
```
let a=[1,4,5,3,7]
let a1=a.reduce((h1,h2)=>{
return h1+h2
})
```
Higher order methods are powerful tools that allow more readable, concise and function-style programming. map(), reduce() and filter() methods are some basic and more important methods which are usually asked in beginners interview.

Hi everyone!
It's [Benedikt](https://x.com/bndkt) again this week, as Sebastien is taking a break.
For me, the week's most interesting topics are not big announcements or new releases but rather subtle hints at future work (type-safe routes models coming to Remix, React Compiler coming to Expo, native intents in Expo Router), as well as some online discussions about React Suspense implementation details (`display: none`, and, more importantly, a pretty significant change in parallel fetching behavior with React 19).

🎥 **[Ryan Florence talk “Mind the Gap”](https://www.youtube.com/live/1g5ruM-16_Y?t=7443s)**
I watched this talk after hearing multiple people describing it as one of the best tech conference talks they’ve ever seen. We’re at a very interesting point in time in web development, with React 19 bringing a major shift to the React model, new JS frameworks gaining popularity, and lots of online discussions drawing distinctions and/or making comparisons to Rails and Laravel. Ryan’s talk is a really good overview of how we got here and it offers, in my opinion, a very good mental model of how to think about React 19. Also fun to see one of the creators of Remix give a Next.js demo 😉

1,888,341 | How to create a database and access specific data from it? | As I learned last time, how to create database using query in terminal. mysql -uroot /*Press enter... | 0 | 2024-06-14T11:09:54 | https://dev.to/ghulam_mujtaba_247/how-to-create-a-database-and-access-specific-data-from-it-1ei9 | webdev, database, php, beginners | As I learned last time, how to create database using query in terminal.
```sql
mysql -uroot
/*Press enter key and then give input to terminal to create database.*/
create database myapp;
```
Now, I need to connect to the database so I can access the table and fetch the specific name.
To connect to the database, you'll need to use PHP code to establish a connection using PDO (PHP Data Objects) or mysqli (MySQL Improved Extension). Here's an example using PDO, firstly we have to know about PDO
## what are PDO's in PHP?
PDO (PHP Data Objects) is a PHP extension that provides a consistent interface for accessing and manipulating databases.
Here are some basic steps to get database accessible and to retrieve data
## Create a new PDO object:
```php
$pdo = new PDO('dsn', 'username', 'password');
```
Here:
- 'dsn' (Data Source Name) specifies the database connection details (e.g. database type, host, database name)
- 'username' and 'password' are the credentials to authenticate by the database
Example:
```php
$pdo=newPDO('mysql:host=localhost;dbname=myapp', 'root', 'password');
```
This creates a connection to a MySQL database named "myapp" on the local host with the username "root" and password "password".
## Prepare a statement to retrieve the name
Here is the statement for retrieving the specific name of an applicant through database.
```php
$stmt = $pdo->prepare('SELECT name FROM applicants WHERE name = :name');
```
## Bind the parameter:
The specific name you're looking for
```php
$stmt->bindParam(':name', $name);
```
## Set the value of $name
Input the name that you want to search in database
```php
$name = 'Ali Hasan';
```
## Execute query to fetch result
After inputing the name in `$name` variable then next step is execution of statement. As the execution is completed then fetch the result
```php
$stmt->execute();
$result = $stmt->fetch();
```
## Display the result
Now you have to write the statement to display the result that you have fetched through database
```php
echo $result['name'];
```
## Close the database connection
At the end of search you have to close the connection through database using PDO variable with null value.
```php
$pdo = null;
```
I hope that you have understand it completely. | ghulam_mujtaba_247 |
1,888,340 | Taming the Chaos: My Personal Practical Tips for Wrangling Messy Data | Ah, data. The lifeblood of data science, the fuel for powerful insights. But let's be honest,... | 0 | 2024-06-14T11:09:40 | https://dev.to/fizza_c3e734ee2a307cf35e5/taming-the-chaos-my-personal-practical-tips-for-wrangling-messy-data-2imb | datascience, wrangling, data, ai | Ah, data. The lifeblood of data science, the fuel for powerful insights. But let's be honest, real-world data is rarely pristine. In fact, it's more often a tangled mess of inconsistencies, missing values, and formatting oddities. This is where the art (and science) of data wrangling comes in.
Data wrangling, also known as data cleaning, is the essential process of transforming raw data into a usable format. It's the unglamorous hero of data science, the silent warrior that ensures your analysis is built on a solid foundation.
_So, how do you wrangle this unruly beast? Here are some practical tips to get you started:_
**1. Embrace the Power of Visualization:**
Before diving in, get a feel for your data's landscape. Use histograms, scatter plots, and boxplots to identify outliers, missing values, and data distribution patterns. Visualization is your key to understanding the nature of the beast you're about to tame.
**2. Identify and Address Missing Values:**
Missing data points are a common foe. There are several strategies to deal with them, depending on the context. You can simply remove rows with missing values, but this might not be ideal if you have a large dataset. Alternatively, you can fill in missing values using techniques like mean imputation or median imputation.
**3. Consistency is Key:**
Data inconsistencies can throw a wrench into your analysis. Inconsistent formatting, for example, can make it difficult to compare values. Standardize your data by ensuring consistent date formats, units of measurement, and capitalization throughout your dataset.
**4. Harness the Power of Regular Expressions:**

1,888,336 | Arquitetura de Microservices: O Futuro da Construção de Sistemas Escaláveis | Nos últimos anos, a arquitetura de microservices tem ganhado popularidade entre desenvolvedores e... | 0 | 2024-06-14T11:06:34 | https://dev.to/iamthiago/arquitetura-de-microservices-o-futuro-da-construcao-de-sistemas-escalaveis-1mnc | Nos últimos anos, a arquitetura de microservices tem ganhado popularidade entre desenvolvedores e empresas de tecnologia. Este modelo arquitetural oferece uma abordagem modular para o desenvolvimento de software, permitindo que as aplicações sejam divididas em componentes menores e independentes, conhecidos como "microservices". Neste artigo, exploraremos os conceitos fundamentais dos microservices, suas vantagens e desafios, e como implementá-los com sucesso em seu projeto.
## O Que São Microservices?
Microservices, ou microsserviços, são uma abordagem arquitetural onde uma aplicação é estruturada como um conjunto de serviços pequenos e independentes. Cada serviço é responsável por uma funcionalidade específica e se comunica com outros serviços através de APIs bem definidas. Ao contrário da arquitetura monolítica tradicional, onde todos os componentes estão interligados em uma única aplicação, os microservices permitem que cada componente seja desenvolvido, implantado e escalado de forma independente.
## Vantagens dos Microservices
### 1. Escalabilidade
Uma das principais vantagens dos microservices é a escalabilidade. Em uma arquitetura monolítica, escalar uma aplicação muitas vezes significa replicar toda a aplicação, o que pode ser ineficiente e custoso. Com microservices, é possível escalar apenas os componentes que realmente necessitam de mais recursos, otimizando o uso de infraestrutura e reduzindo custos.
### 2. Flexibilidade Tecnológica
Microservices permitem a utilização de diferentes tecnologias para cada serviço. Isso significa que uma equipe pode escolher a linguagem de programação ou o framework que melhor se adapta àquela funcionalidade específica, sem estar presa a uma única stack tecnológica para toda a aplicação.
### 3. Implantação Independente
A capacidade de implantar serviços de forma independente permite que as atualizações sejam realizadas com menor impacto no sistema como um todo. Isso facilita a manutenção e a introdução de novas funcionalidades, além de reduzir o tempo de inatividade.
### 4. Resiliência
Com microservices, falhas em um serviço não necessariamente comprometem toda a aplicação. Isso torna o sistema mais resiliente, pois cada serviço pode ser projetado com seus próprios mecanismos de recuperação e redundância.
## Desafios dos Microservices
### 1. Complexidade de Gestão
A gestão de múltiplos serviços pode se tornar complexa, especialmente à medida que o número de microservices cresce. Ferramentas de orquestração como Kubernetes podem ajudar a gerenciar essa complexidade, mas ainda assim requerem um nível significativo de experiência e conhecimento.
### 2. Comunicação e Latência
Microservices dependem de comunicação inter-serviços, geralmente através de redes. Isso pode introduzir latência e aumentar a complexidade de depuração e monitoramento. Implementar padrões como Circuit Breaker e Service Mesh pode ajudar a mitigar esses problemas.
### 3. Consistência de Dados
Garantir a consistência de dados em um sistema distribuído é um desafio. Estratégias como a coordenação de transações distribuídas e o uso de Event Sourcing podem ser necessárias para manter a integridade dos dados.
## Boas Práticas na Implementação de Microservices
### 1. Defina Limites Claros
Definir limites claros entre os serviços é crucial. Utilize técnicas como Domain-Driven Design (DDD) para identificar os contextos delimitados e garantir que cada microservice tenha uma responsabilidade bem definida.
### 2. Automação de DevOps
A automação é essencial para o sucesso dos microservices. Utilize pipelines de CI/CD para automatizar o processo de build, teste e implantação. Ferramentas como Docker e Kubernetes são fundamentais para criar um ambiente consistente e escalável.
### 3. Monitoramento e Logging
Implemente uma solução robusta de monitoramento e logging para rastrear a performance e diagnosticar problemas. Ferramentas como Prometheus, Grafana e ELK Stack são populares nesse espaço.
### 4. Gestão de Configuração
Centralize a gestão de configuração utilizando ferramentas como Consul ou Spring Cloud Config. Isso facilita a alteração de configurações sem a necessidade de reimplantar os serviços.
### 5. Segurança
Implemente práticas de segurança desde o início, como autenticação e autorização robustas, encriptação de dados em trânsito e repouso, e monitoramento contínuo de vulnerabilidades.
## Conclusão
A arquitetura de microservices oferece uma maneira poderosa de construir sistemas escaláveis e resilientes, mas também traz novos desafios que precisam ser cuidadosamente gerenciados. Ao adotar boas práticas e ferramentas adequadas, é possível tirar proveito dos benefícios dos microservices e criar aplicações modernas e eficientes.

### Introduction
In the dynamic world of web development, ReactJS and NextJS have emerged as two powerful tools for building modern web applications. While ReactJS provides a robust foundation for creating user interfaces, NextJS extends its capabilities by offering server-side rendering and other advanced features. This post will delve into the key differences between ReactJS and NextJS, providing insights and examples to help you choose the right framework for your next project.
---
### 1. **Overview**
**ReactJS:**
- A JavaScript library developed by Facebook.
- Focuses on building reusable UI components.
- Provides client-side rendering.
**NextJS:**
- A framework built on top of ReactJS.
- Offers server-side rendering, static site generation, and API routes.
- Developed by Vercel.
**Example:**
```jsx
// ReactJS component
import React from 'react';
function HelloWorld() {
return <h1>Hello, World!</h1>;
}
export default HelloWorld;
// NextJS page
import React from 'react';
function HomePage() {
return <h1>Welcome to NextJS!</h1>;
}
export default HomePage;
```
---
### 2. **Rendering Methods**
**Client-Side Rendering (CSR) in ReactJS:**
- The entire application is rendered in the browser.
- Initial load may be slower due to JavaScript parsing.
**Server-Side Rendering (SSR) in NextJS:**
- HTML is generated on the server for each request.
- Improves performance and SEO.
**Static Site Generation (SSG) in NextJS:**
- HTML is generated at build time.
- Fast load times and can be cached by CDNs.
**Example:**
```jsx
// CSR in ReactJS
import React from 'react';
import ReactDOM from 'react-dom';
function App() {
return <h1>Hello from CSR!</h1>;
}
ReactDOM.render(<App />, document.getElementById('root'));
// SSR in NextJS
export async function getServerSideProps() {
return {
props: { message: 'Hello from SSR!' },
};
}
function SSRPage({ message }) {
return <h1>{message}</h1>;
}
export default SSRPage;
// SSG in NextJS
export async function getStaticProps() {
return {
props: { message: 'Hello from SSG!' },
};
}
function SSGPage({ message }) {
return <h1>{message}</h1>;
}
export default SSGPage;
```
---
#### 3. **Routing**
**ReactJS:**
- Uses third-party libraries like React Router.
- Client-side routing.
**NextJS:**
- Built-in file-based routing.
- Supports dynamic routes and API routes.
**Example:**
```jsx
// React Router in ReactJS
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
function App() {
return (
<Router>
<Switch>
<Route path="/about">
<About />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
</Router>
);
}
// File-based routing in NextJS
// pages/index.js
function Home() {
return <h1>Home Page</h1>;
}
export default Home;
// pages/about.js
function About() {
return <h1>About Page</h1>;
}
export default About;
```
---
#### 4. **Data Fetching**
**ReactJS:**
- Data fetching is done through hooks like `useEffect`.
- Typically uses libraries like Axios or Fetch API.
**NextJS:**
- Provides built-in methods like `getStaticProps`, `getServerSideProps`, and `getStaticPaths`.
- Supports both static and server-side data fetching.
**Example:**
```jsx
// Data fetching in ReactJS
import React, { useEffect, useState } from 'react';
import axios from 'axios';
function DataFetchingComponent() {
const [data, setData] = useState(null);
useEffect(() => {
axios.get('/api/data').then(response => {
setData(response.data);
});
}, []);
return <div>{data ? data : 'Loading...'}</div>;
}
// Data fetching in NextJS
// pages/data.js
export async function getStaticProps() {
const res = await fetch('https://api.example.com/data');
const data = await res.json();
return {
props: {
data,
},
};
}
function DataPage({ data }) {
return <div>{data ? data : 'Loading...'}</div>;
}
export default DataPage;
```
---
### 5. **Performance**
**ReactJS:**
- Performance depends on client-side rendering optimizations.
- Can use React.memo and useCallback to improve performance.
**NextJS:**
- Offers better performance out-of-the-box with SSR and SSG.
- Built-in image optimization and faster initial page load.
**Example:**
```jsx
// Performance optimization in ReactJS
import React, { useCallback, useState } from 'react';
const ExpensiveComponent = React.memo(({ compute }) => {
return <div>{compute()}</div>;
});
function App() {
const [count, setCount] = useState(0);
const compute = useCallback(() => count * 2, [count]);
return (
<div>
<ExpensiveComponent compute={compute} />
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
// Performance in NextJS
// No additional code needed for basic optimizations
```
---
### 6. **Development Experience**
**ReactJS:**
- Requires more setup and configuration.
- Flexible and unopinionated, allowing for various setups.
**NextJS:**
- Minimal configuration with sensible defaults.
- Full-stack capabilities with API routes and middleware support.
**Example:**
```jsx
// Setting up ReactJS
// Requires installing packages like react, react-dom, and webpack
// Setting up NextJS
// Minimal setup with `npx create-next-app`
```
---
### Conclusion
ReactJS and NextJS serve different purposes and can complement each other. ReactJS is ideal for building highly interactive UIs, while NextJS enhances React's capabilities with server-side rendering, static site generation, and more. Understanding their differences and strengths will help you choose the right tool for your project, ensuring optimal performance, scalability, and development experience.

Hello, amazing people and welcome back to my blog! Today we're going to build a practical example in Rust where we are going to explore the async-await. it will be a web crawler with `Surf` and `Async-Std`.
## Dependencies
**Let's start with the `Cargo.toml` file:**
We'll need 4 things:
* `async-std` is the standard Rust library for async-await
* `surf` is an HTTP client which utilizes the async-await
* `html5ever` is a module from the `servo` project, which will allow us to parse the HTML we get
* `url` is a library that will allow us to determine whether or not the URLs that we're getting from the web pages that we're pinging to are valid.
```ini
async-std = "1.2.0"
surf = "1.0.3"
html5ever = "0.25.1"
url = "2.1.0"
```
**Let's go to the `main.rs` file:**
The first thing we want to do with this application is write the internal logic so that we can parse the HTML and identify the proper tags that we need to get the URLs that are on the page.
We'll be bringing in a lot of stuff from the `html5ever`, and more specifically from the `tokenizer.` We'll bring in the `BufferQueue, Tag, TagKind, TagToken, Token, TokenSink, TokenSinkResult, Tokenizer, TokenizerOpts.` Also, we're going to need `use std::borrow::Borrow;`, and `use url::{ParseError, Url};` .
*As we continue our program we'll return back to importing a couple of more things :)*
```rust
use html5ever::tokenizer::{
BufferQueue, Tag, TagKind, TagToken, Token, TokenSink, TokenSinkResult, Tokenizer,
TokenizerOpts,
};
use std::borrow::Borrow;
use url::{ParseError, Url};
```
## Struct and Implementation
As you can imagine, as we're crawling over a web page we're going to have a lot of links, so we want to create a `struct` that will allow us to keep all those links inside of a nice vector. We'll call it `LinkQueue` (it'll contain all of the links that we'll be crawling.)
For the `LinkQueuestruct`, we want to `#[derive(Default, Debug)]` so that we can `Default` the values in the struct. Because we want to be able to see all of the links inside of the queue, we'll derive the `Debug` trait on top of it.
```rust
#[derive(Default, Debug)]
struct LinkQueue {
links: Vec<String>,
}
```
For us to be able to use the `Tokenizer` from `html5ever`, we want to take the `TokenSink` trait and implement it on our `LinkQueue` struct, and because our `LinkQueue` is going to be mutable, we'll do it like this: `impl TokenSink for &mut LinkQueue`.
Now the `TokenSink` trait has a few things attached to it! We'll also need a `process_token` function which will be essentially the main function.
`process_token` needs to take in a reference to mutable `self`, so mutable `LinkQueue`, and then it will take in the `token` type, and then the `line_number`, and then it will output a `TokenSinkResult`, and since the `Handle` will be a `union` type (`type Handle = ();`), we'll put that `Handle` inside of the result.
The `TokenSinkResult` type is an `enum` type, and we can use this `enum` type to specify what we want our function to do after it passes over one of our tokens. So once we find a link, we want our function to continue to parse the rest of the HTML to find all of the rest of the links, so we can use the `TokenSinkResultContinue` type as our return type from our process function (`TokenSinkResult::Continue`).
```rust
impl TokenSink for &mut LinkQueue {
type Handle = ();
// <a href="link">some text</a>
fn process_token(&mut self, token: Token, line_number: u64) -> TokenSinkResult<Self::Handle> {
match token {
TagToken(
ref tag @ Tag {
kind: TagKind::StartTag,
..
},
) => {
if tag.name.as_ref() == "a" {
for attribute in tag.attrs.iter() {
if attribute.name.local.as_ref() == "href" {
let url_str: &[u8] = attribute.value.borrow();
self.links
.push(String::from_utf8_lossy(url_str).into_owned());
}
}
}
}
_ => {}
}
TokenSinkResult::Continue
}
}
```
But before we return this `TokenSinkResult` of `Continue` type, we want to `match` on the `token` itself. The `token` type that we'll be matching on has a bunch of different values this is because it's an `enum`. The one that we're worried about is just the `TagToken`.
So the `TagToken` means that it's a normal HTML tag, and that's what we're looking for. To make our pattern `match` exhaustive, we can set it up so that we look for the tag type specifically, and then we have a catch-all which catches the rest and throws them out.
Each `tag` inside of an HTML document has two pieces to it: It has an opening tag and a closing tag. Inside of our code, the `TagKind` can either be a `StartTag`, which is this opening piece, or it can be an `EndTag`, which is the closing piece.
We're specifically looking for the links inside of `a` tags, so we want to look inside of the `StartTag`. We can do a pattern match on the `TagKind`, and we can say specifically that we want to look at tags where the `kind` of the `tag` is a `StartTag`. Once we've determined that the `tag` is a `StartTag`, we can go ahead and just run an `if` check to if the tag name is `a` (`tag.name.as_ref() == "a"`). Opening tags can have multiple attributes inside of them, so we want to take the `tag` that we've identified, grab the `attributes`, and then iterate through all of them (`for attribute in tag.attrs.iter()`). Then we can check if the attribute's local name is `href` (`if attribute.name.local.as_ref() == "href"`).
After all of these checks, we know that we're looking at the `url_str`. We can go ahead and grab the `url_str` by calling `attribute.value.borrow()`. This will allow us to get the value of the URL. Then, we want to borrow it so that we can push it into our links vector (`let url_str: &[u8] = attribute.value.borrow();`). The value we're getting from the attribute will come in as a slice of `u8` numbers because it's being read in as bytes. We want to convert those bytes into a string when we `push` it into our `LinkQueue`, it takes these in as a reference to `u8`, and then we call `String::from_utf8_lossy(url_str)` on our `url_str`, finally, we convert it into an `url_str` as we push it into our links vector.
## get_links function
Let's continue by creating a function called `get_links`, this will take in a `url` and a `page`, and it will pass back a vector of URLs. First, we want to make sure that the URL is just the `domain_url`, and we can do this by taking the URL that we pass into the function and cloning it into a mutable variable called `domain_url`.
```rust
pub fn get_links(url: &Url, page: String) -> Vec<Url> {
let mut domain_url = url.clone();
domain_url.set_path("");
domain_url.set_query(None);
```
We can instantiate one of our link queues by using the default method, and this will zero out the links vector inside of our `LinkQueue`.
```rust
let mut queue = LinkQueue::default();
let mut tokenizer = Tokenizer::new(&mut queue, TokenizerOpts::default());
let mut buffer = BufferQueue::new();
```
With our `LinkQueue`, we can now go ahead and create the HTML `Tokenizer`. We pass the `LinkQueue` into `Tokenizer` as a mutable reference. For the tokenizer options, we can pass in `TokenizerOpts::default()`. Let's now create a buffer queue, `let mut buffer = BufferQueue::new();`. The `BufferQueue` will allow us to essentially go through our `page: String` one item at a time. It's essentially what's responsible for reading through the characters in our HTML page. The tokenizer on the other hand is what's responsible for identifying the tokens in the HTML document.
```rust
buffer.push_back(page.into());
let _ = tokenizer.feed(&mut buffer);
```
Now let's take our `page: String` and push it into the `BufferQueue.` Now we can take that buffer and `feed` it into our `tokenizer`. Once we've done this, we can take all of the links, which will be fed into our `LinkQueue`, iterate through them, and then `map` on top of them to check what kind of URLs we have.
```rust
queue
.links
.iter()
.map(|link| match Url::parse(link) {
Err(ParseError::RelativeUrlWithoutBase) => domain_url.join(link).unwrap(),
Err(_) => panic!("Malformed link found: {}", link),
Ok(url) => url,
})
.collect()
}
```
We call `Url::parse` on each of the links inside of our links vector. This will allow us to determine whether or not we have a valid URL.
There's one error case that we want to specifically look for and that is to check if URL is a relative URL (`RelativeUrlWithoutBase`). That is to say that it doesn't have the domain attached to it. On web pages, it's not uncommon to just put in the relative URL rather than the absolute URL. If we want to deal with this case, and we don't just want to throw out all of the links that are directly connected to whatever domain we're searching on what we can do is take those relative URLs and attach them to the domain URL, and then pass them back as a new absolute URL. Then if we get any other kind of error, we can just `panic` and say that we have `Malformed link found: {}`, and then we can print out that `link`.
If we have a normal URL, then we'll get back `Ok` and the URL, and we can pass that back. To finish this off, we want to collect all of these URLs into a vector. We can call the `collect` method on our `map` function.
## crawl function
If we were to feed an HTML document into the above function, it would properly scan over the HTML and find all of the links that were associated with it. But of course, we want to be able to call a server using a URL, and then have that server feed us the HTML. So let's try to accomplish this!
We need to make two more imports. We need to import `async_std::task`, and we need to import the `surf` client.
```rust
use async_std::task;
use surf;
```
Let's create some helper types. We'll create a type called `CrawlResult`, which will be a `Result` type:
`type CrawlResult = Result<(), Box<dyn std::error::Error + Send + Sync + 'static>>;`
Next, we have a `BoxFuture` type which will be surrounded by a standard library `pin`. The `pin` is essentially just a pinned pointer. Inside of this pin pointer, we'll have another box. And inside of the box, we'll have an implementation of a standard `future`, where the output is a `CrawlResult`, which is that other type that we just created!
`type BoxFuture = std::pin::Pin<Box<dyn std::future::Future<Output = CrawlResult> + Send>>;`
With these helper types we are saying that inside of both of these boxes, we want to return a type that implements the trait.
**Now, we can go ahead and create a function called**`crawl`**!**
```rust
async fn crawl(pages: Vec<Url>, current: u8, max: u8) -> CrawlResult {
println!("Current Depth: {}, Max Depth: {}", current, max);
if current > max {
println!("Reached Max Depth");
return Ok(());
}
.
.
}
```
Our `crawl` function will return a future type. So even though we've specified that we want to return the `CrawlResult`, we're actually returning a future that's wrapped around the `CrawlResult` by specifying that this function is asynchronous. The `CrawlResult` takes in a vector of URL, which will be our pages (`pages: Vec<Url>`), it takes in the current depth, which will be a u8 value ( `current: u8`) and then it takes in the max depth, which will also be a u8 value (`max: u8`). These depths determine how many pages from the original page we want to crawl. Let's also print out the current depth and the max depth `("Current Depth: {}, Max Depth: {}", current, max)`.
Then we want to check if `current > max` because if it is, then we want to stop crawling.
```rust
let mut tasks = vec![];
println!("crawling: {:?}", pages);
for url in pages {
let task = task::spawn(async move {
println!("getting: {}", url);
let mut res = surf::get(&url).await?;
let body = res.body_string().await?;
let links = get_links(&url, body);
println!("Following: {:?}", links);
.
.
.
});
tasks.push(task);
}
```
Essentially what we're going to do is `spawn` multiple different tasks for each of the URLs that we get and each of these tasks will spin up what's called a green thread. So they'll run asynchronously to one another. We can create a vector for all of our tasks and print out that we're crawling over all of these pages `println!("crawling: {:?}", pages);`.
Now for each URL inside of our `pages` vector, we want to `spawn` a specific task that is `spawn` one of these green threads. For each of our tasks, we'll go ahead and we'll print out that we're getting that URL `println!("getting: {}", url);` Then we'll go and use the `surf` library to call a `get` method on that URL: `let mut res = surf::get(&url).await?;`.
After we've got the result back from calling `surfget`, we'll take that result and get the `body_string`, which again will give us back a future, which we want to wait on (`let body = res.body_string().await?;`). We'll wait until we get that entire `body_string` before we move forward and call our `get_links` function on both the `url` and the `body_string`.
`let links = get_links(&url, body);`
We can print out that we're following all of the links (`println!("Following: {:?}", links);`) that were inside of the `body_string` that we passed to our `get_links` function and after we've done all these, we can take the task that we created and push it into our tasks vector. It's important to keep in mind that even though we're generating tasks here, we haven't actually tried to execute them yet! We're just putting them inside of our tasks vector. To execute them, we need to take them out of the tasks vector and then call a `wait` on them. Essentially what we're doing is just going through each of the URLs, getting them from our pages and then spawning tasks for each URL so that we can continue to follow them. To continue to follow them, we want to recursively call our `crawl` function after we get all of the links on each of the links.
## box\_crawl function
So what we want to do is set up another function that puts our `crawl` function inside of a `Box` pointer. We'll create a wrapper function called `box_crawl`, which takes in the `pages`, the current depth and the max depth, and it returns our `BoxFuture` type.
```rust
fn box_crawl(pages: Vec<Url>, current: u8, max: u8) -> BoxFuture {
Box::pin(crawl(pages, current, max))
}
```
In the function, we create a new `Box::pin(crawl(pages, current, max))` and we put our `crawl` function call inside of it.
Now we can return into our `crawl` function and pass a call to `box_crawl`, pass in the `links`, then take our `current` depth and add 1 to it, and then also pass in the `max` depth.
```rust
box_crawl(links, current + 1, max).await
```
Now we're finished with our crawler logic!
## main function
Let's finish up our application by tying our main function.
```rust
fn main() -> CrawlResult {
task::block_on(async {
box_crawl(vec![Url::parse("https://www.rust-lang.org").unwrap()], 1, 2).await
})
}
```
We'll call the `box_crawl` and as an example, I'm using the [`rustlang.org`](http://rustlang.org) website. Then I'm putting in a current depth of `1` and a max depth of `2`.
## Run it
Now, we can go ahead and run this application with `cargo run`. It goes through all of the different links and it follows them as we would expect with a web crawler. If right now you run the same example as me ([`rustlang.org`](http://rustlang.org)`,`current depth of `1` and a max depth of `2`), you can see there are quite a lot of things!

1,888,323 | Quick Django Installation Script | I work with Django projects frequently, and often find myself repeating the same commands during... | 0 | 2024-06-14T10:50:06 | https://dev.to/stacknatic/quick-django-installation-script-2fa9 | I work with [Django projects](https://stacknatic.com/blog/why-i-switched-to-headless-django-with-nextjs) frequently, and often find myself repeating the same commands during Django installation.
To streamline the initialization of Django projects, I created an installation script for easy setup, which I’m sharing in this post. The script is a bash script designed to work seamlessly on Ubuntu 22 and should also be compatible with other versions. If you are using MacOs, you can simply remove the part that begins with '# Update package list and install dependencies' up until the next 'fi' line or comment out the block. While it is not strictly necessary to update your system before installing Django, it is generally a good practice to ensure your system is up to date.
What the script does:
1. It checks for system updates. If updates are available, it will attempt to update your system.
2. Creates a virtual environment for Django. If you’re new to Python development or the ecosystem, virtual environments are useful for isolating your project’s dependencies from other Python projects on your system. This ensures that any packages or libraries required by your Django project are installed and managed separately, avoiding conflicts and keeping your environment clean and organized.
3. Installs Django.
4. Starts the Django application, which you can access at http://127.0.0.1:8000 in your web browser.
```
#!/bin/bash
# Function to check the last command status

1,888,322 | Why DeFi Integration Is Essential for Business Growth in the Digital Economy? | In a time where technology is constantly changing the way businesses operate, decentralized finance... | 0 | 2024-06-14T10:49:37 | https://dev.to/anne69318/why-defi-integration-is-essential-for-business-growth-in-the-digital-economy-3h3i | In a time where technology is constantly changing the way businesses operate, decentralized finance (DeFi) is becoming a major factor in the transformation of the economy. Compared to conventional systems, DeFi's cutting-edge financial solutions are more transparent, easily accessible, and effective since they make use of blockchain technology. Integrating DeFi is not merely a choice, but a must for companies looking to prosper in the digital age. These are five strong arguments for why DeFi integration is crucial to the expansion of your company.
-
**Enhanced Financial Accessibility and Inclusion**
DeFi makes financial services accessible to companies of all sizes and geographical locations by removing the obstacles put in place by traditional financial institutions. Without the need for a centralized middleman, even startups and SMEs will be able to manage assets, make investments, and get loans thanks to this democratization of finance.
-
**Cost Efficiency and Increased Profit Margins**
Conventional financial services frequently have expensive costs and protracted processing periods. Conversely, DeFi systems run on blockchain technology, which lowers transaction costs and speeds up the settlement procedure. Businesses benefit directly from this cost efficiency in the form of higher profit margins.
-

However, native mobile apps can be expensive to develop, require downloads from app stores, and take up valuable storage space on phones. This is where Progressive Web Apps (PWAs) shine - offering a powerful and user-friendly alternative.
This article cuts through the technical jargon to focus on the big picture.
> Do you wish to learn all the secrets behind PWAs? <br>Check my [PWA course](https://www.educative.io/courses/zero-to-hero-with-progressive-web-apps) teaching you in detail how to develop and optimize PWAs with ease.
## What are Progressive Web Apps (PWAs)?
A PWA is a web application that, thanks to modern technologies, can provide extended and rich features to users.
Below is a screenshot of the Twitter/X native app for Android and its PWA version. Once a PWA is installed on a device, it is almost impossible to distinguish it from a native app.
One of the goals of Progressive Web Apps is exactly to combine the accessibility and discoverability of a website with the functionality and user experience (UX) of a native app. Our customers can access the PWA directly from their web browser, without any download required from an app store.
## PWAs Core Parts
Two key components can make PWAs installable and working offline: the **web manifest** file and **service workers**.
### Web Manifest
> A web manifest file can be seen as a blueprint for our PWA.
It instructs the browser agent that our PWA can be installed on the home screen, just like a native app. An *install banner* (named A2HS - Add To Home Screen) is automatically displayed on the user's device. It also specifies essential visual details like the app's name, icon, and if we want to display the application in portrait (vertical) or landscape (horizontal) mode. The latter is the preferred option for media-rich content or web games.
Thanks to the `display` property of the manifest file we can instruct whether the browser's UI elements (e.g. URL address bar) should be rendered or less. <br>
Three main values are possible (in the pictures below from left to right respectively):
- _browser_ (default mobile experience)
- _standalone_
- _fullscreen_
As we can see, with these properties it is possible to remove some UI elements of the browser or even use the whole device's viewport. All these aspects help to create a familiar and app-like feel.
### Service Workers
Let's delve into the engine that powers offline functionality and allows for drastic performance improvements – service workers (SW). These are essentially scripts that run in the background, separate from your PWA's main thread, and can offload our application from heavy tasks. <br>
They act as intermediaries between the app and the network, offering several advantages:
**Caching:** Service workers can intelligently cache essential static resources like HTML pages, JS or CSS files, and HTTP responses as well. This means that when a user visits our PWA, even without an internet connection, the cached resources can be used to deliver a functional, albeit potentially limited, experience.
**Improved Performance:** This aspect relates tightly to the previous point. Responses from the local cache are provided almost instantaneously since no network roundtrip is needed. We can implement multiple caching strategies to cover wide scenarios and ensure that, if needed, the provided cached data is not stale but in an up-to-date state.
**Push Notifications:** SW enables push notifications, a powerful tool for keeping users engaged. Web notifications were for a long time precluded to iOS devices, but since v16.4 are now available for Apple users as well).
Even when the PWA is not actively running, service workers can receive and display notifications, prompting users to revisit your app. This is possible because Service workers run in the background and, therefore do not require the user to be actively on the PWA to perform actions.
**Background Syncing:** This web API allows to register actions (sync tags) that, in case the user does not have a valid internet connection, will be kept *on hold* for later execution.
Once the user regains internet connectivity, service workers are notified by the API and seamlessly synchronize any offline actions taken within the PWA. <br> Imagine we are building an e-commerce website where users can add items to their cart and submit orders. A user adds items to their cart and proceeds to checkout. While filling out the order form, the user's internet connection drops (maybe because of commuting from/to work). Without Background Sync API, the user would lose their order progress, leading to frustration and a new order for our company. This combination of web APIs and service workers ensures data consistency and a smooth user experience in these scenarios.
## Benefits of Native Apps
PWAs offer a multitude of advantages over traditional mobile apps, making them a compelling option for businesses of all sizes:
**Reduced Development Costs**: PWAs leverage existing web development technologies, making them significantly cheaper and faster to develop than native apps. There is no need to have dedicated developer teams to create iOS or Android apps. This translates into substantial cost savings for your business.
**Reduced Time To Market**: PWAs bypass the app store approval process, avoiding potential delays in the release date due to the restrictions or controls imposed by app stores.
**Extended Functionalities**: Thanks to Web APIs, all web apps, PWAs included, can benefit from new and modern features out of the box. For instance, we can interact with the hardware of the hosting mobile phone to detect the amount of light in the surroundings. This allows the development of smart capabilities and switching automatically from a light to a dark theme if the user is in a room with insufficient light. The native app Google Maps has the same behavior, switching to the dark mode when we cross a tunnel while driving, for instance.
**Improved Conversion Rates**: By providing a seamless, app-like experience, PWAs can significantly improve conversion rates, leading to more sales and increased revenue for your business. The website [PWA Stats](https://www.pwastats.com/) collects several success stories of companies that adopted PWAs.
**Search Engine Optimization (SEO) Friendly**: PWAs are indexed by search engines like websites, making it easier for potential customers to discover our business online.
**Easy to Maintain**: Updates to PWAs happen automatically in the background, ensuring users always have access to the latest features and bug fixes without the need to download a new patched version. Differently from a native app, PWAs have only one version live to be maintained.
**Small Memory Footprint**: PWAs do not come with 3rd party libraries as native apps and, therefore require much less space on the hosting device. This can be a crucial aspect for our business if a portion of our user base does not have modern devices or the cost for mobile data is significantly high in their country.
## Conclusion
In conclusion, opting for a progressive web app over a native app can represent a strategic advantage for our business. <br>
PWAs offer a user experience that rivals native apps, reaching a wider audience without the burden of individual app store downloads for a fraction of the development costs. This streamlined approach translates to broader customer accessibility and increased engagement, ultimately driving growth for our company. | paco_ita |

const option={
editor: new InputEditor()
}
```
After configuration, you can click on any cell to edit it.
1. If a few columns can share the same editor, you can declare the same editor name in the columns column configuration for reuse.
```
import { DateInputEditor, InputEditor, ListEditor, TextAreaEditor } from '@visactor/vtable-editors';
const input_editor = new InputEditor();
VTable.register.editor('input-editor', input_editor);
const option={
columns:[
{field:'id',title: 'ID'},
{field:'name',title: 'NAME',editor:'input-editor'},
{field:'address',title: 'ADDRESS',editor:'input-editor'},

1,888,313 | Enhanced Secure Session Management in JavaScript Web Applications | In today's digital age, securing user sessions is paramount to maintaining the integrity and... | 0 | 2024-06-14T10:42:41 | https://dev.to/saumya27/enhanced-secure-session-management-in-javascript-web-applications-4dp | javascript, webdev, programming | In today's digital age, securing user sessions is paramount to maintaining the integrity and confidentiality of web applications. Secure session management involves practices and mechanisms that ensure the protection of user sessions from unauthorized access and attacks. This blog explores the critical aspects of secure session management and best practices to implement it effectively.
**Understanding Session Management**
A session in web applications represents a series of interactions between a user and the application, typically managed by a session ID. This session ID is stored on the client side, usually in a cookie, and sent to the server with each request to maintain the user's state.
**Key Components of Secure Session Management**
**Session ID Generation**
Uniqueness and Randomness: Ensure session IDs are unique and randomly generated to prevent session fixation attacks. Use strong cryptographic functions to generate session IDs.
Length and Complexity: Session IDs should be sufficiently long and complex to resist brute-force attacks. A typical session ID should be at least 128 bits in length.
**Session ID Storage and Transmission**
Use Secure Cookies: Store session IDs in secure, HttpOnly cookies to prevent access via JavaScript. Set the Secure attribute to ensure cookies are only sent over HTTPS.
Transmission over HTTPS: Always use HTTPS to encrypt the transmission of session IDs, protecting them from interception and man-in-the-middle attacks.
**Session Timeout and Expiry**
Idle Timeout: Implement idle timeout to automatically log out users after a period of inactivity. This reduces the risk of unauthorized access from unattended sessions.
Absolute Timeout: Set an absolute timeout to limit the maximum duration of a session, forcing users to re-authenticate after a certain period.
**Session Hijacking Prevention**
IP Address and User-Agent Binding: Bind sessions to the user's IP address and User-Agent string. If a request comes from a different IP address or User-Agent, prompt re-authentication.
Session Regeneration: Regenerate session IDs upon login, privilege changes, and periodically during a session to prevent session fixation attacks.
**Secure Logout Mechanism**
Proper Session Termination: Ensure that logging out properly terminates the session on the server side. Invalidate the session ID and delete the cookie from the client side.
CSRF Protection: Implement Cross-Site Request Forgery (CSRF) tokens to protect against CSRF attacks, which can hijack active sessions.
**Best Practices for Secure Session Management**
- Use Modern Frameworks and Libraries
Leverage modern web frameworks and libraries that provide built-in secure session management features, reducing the risk of implementing insecure practices.
- Monitor and Audit Sessions
Regularly monitor active sessions for suspicious activities. Implement logging and auditing to detect and respond to potential security incidents promptly.
- Educate Users
Educate users about the importance of logging out from shared or public computers and recognizing phishing attempts to protect their sessions.
- Stay Updated with Security Trends
Stay informed about the latest security trends and vulnerabilities related to session management. Regularly update your application and dependencies to mitigate new threats.
**Conclusion**
[Secure session management](https://cloudastra.co/blogs/enhanced-secure-session-management-in-javascript-web-applications) is a crucial aspect of web application security, safeguarding user data and maintaining trust. By implementing robust session management practices, including secure session ID generation, storage, and transmission, as well as timely session expiration and user education, you can significantly enhance the security of your web applications. Prioritizing these measures helps protect against common session-based attacks, ensuring a secure and seamless user experience. | saumya27 |

We have implemented the editable table business scenario using the editing capabilities provided by VTable. However, there is a requirement to delete the content of the selected cell when the delete key or backspace key is pressed on the keyboard.
## Solution
Currently, VTable itself does not support this feature. You can implement it yourself by listening for keyboard events and calling the VTable interface to update cell values.
First, listen for the keydown event and call the changeCellValue interface to update cell values in the event.
See the demo for implementation logic: https://visactor.io/vtable/demo/interaction/context-menu.
```
// 监听键盘事件
document.addEventListener('keydown', (e) => {
if (e.key === 'Delete'||e.key === 'Backspace') {
let selectCells = tableInstance.getSelectedCellInfos();
if (selectCells?.length > 0) {
// 如果选中的是范围，则删除范围内的所有单元格
deleteSelectRange(selectCells);
} else {
// 否则只删除单个单元格
tableInstance.changeCellValue(args.col, args.row, '');
}
}
});
//将选中单元格的值设置为空
function deleteSelectRange(selectCells) {
for (let i = 0; i < selectCells.length; i++) {
for (let j = 0; j < selectCells[i].length; j++) {
tableInstance.changeCellValue(selectCells[i][j].col, selectCells[i][j].row, '');
}
}
}
```
## Code Examples
```
let tableInstance;
fetch('https://lf9-dp-fe-cms-tos.byteorg.com/obj/bit-cloud/VTable/North_American_Superstore_data.json')
.then(res => res.json())

1,888,307 | The File Class | The File class contains the methods for obtaining the properties of a file/directory and for renaming... | 0 | 2024-06-14T10:37:11 | https://dev.to/paulike/the-file-class-f7h | java, programming, learning, beginners | The **File** class contains the methods for obtaining the properties of a file/directory and for renaming and deleting a file/directory. Having learned exception handling, you are ready to step into file processing. Data stored in the program are temporary; they are lost when the program terminates. To permanently store the data created in a program, you need to save them in a file on a disk or other permanent storage device. The file can then be transported and read later by other programs. Since data
are stored in files, this section introduces how to use the **File** class to obtain file/directory properties, to delete and rename files/directories, and to create directories. The next section introduces how to read/write data from/to text files.
Every file is placed in a directory in the file system. An _absolute file name_ (or _full name_) contains a file name with its complete path and drive letter. For example, **c:\book\Welcome.java** is the absolute file name for the file **Welcome.java** on the Windows operating system. Here **c:\book** is referred to as the _directory path_ for the file. Absolute file names are machine dependent. On the UNIX platform, the absolute file name may be **/home/liang/book/Welcome.java**, where **/home/liang/book** is the directory path for the file **Welcome.java**.
A **relative file name** is in relation to the current working directory. The complete directory path for a relative file name is omitted. For example, **Welcome.java** is a relative file name. If the current working directory is **c:\book**, the absolute file name would be **c:\book\Welcome.java**.
The **File** class is intended to provide an abstraction that deals with most of the machine-dependent complexities of files and path names in a machine-independent fashion. The **File** class contains the methods for obtaining file and directory properties and for renaming and deleting files and directories, as shown in Figure below. However, _the File class does not contain the methods for reading and writing file contents_.
The file name is a string. The **File** class is a wrapper class for the file name and its directory path. For example, **new File("c:\\book")** creates a **File** object for the directory **c:\book**, and **new File("c:\\book\\test.dat")** creates a **File** object for the file **c:\book\test.dat**, both on Windows. You can use the **File** class’s **isDirectory()** method to check whether the object represents a directory, and the **isFile()** method to check whether the object represents a file.
The directory separator for Windows is a backslash (**\**). The backslash is a special character in Java and should be written as **\\** in a string literal. _Constructing a **File** instance does not create a file on the machine._ You can create a **File** instance for any file name regardless whether it exists or not. You can invoke the **exists()** method on a **File** instance to check whether the file exists.
Do not use absolute file names in your program. If you use a file name such as **c:\\book\\Welcome.java**, it will work on Windows but not on other platforms. You should use a file name relative to the current directory. For example, you may create a **File** object using **new File("Welcome.java")** for the file **Welcome.java** in the current directory. You may create a **File** object using **new File("image/us.gif")** for the file **us.gif** under the **image** directory in the current directory. The forward slash (**/**) is the Java directory separator, which is the same as on UNIX. The statement **new File("image/us.gif")** works on Windows, UNIX, and any other platform.
The program below demonstrates how to create a **File** object and use the methods in the **File** class to obtain its properties. The program creates a **File** object for the file **us.gif**. This file is stored under the **image** directory in the current directory.
The **lastModified()** method returns the date and time when the file was last modified, measured in milliseconds since the beginning of UNIX time (00:00:00 GMT, January 1, 1970). The **Date** class is used to display it in a readable format in lines 16. | paulike |

title: VSCode DevContainer setup for C/C++ programmers
published: true
date: 2024-06-14 10:35:20 UTC
tags: C,C,devcontainer,vscode
canonical_url: https://blog.mandraketech.in/vscode-devcontainer-setup-for-cpp-programmers
---
This article delves into getting a VS Code DevContainer Development environment based setup for early C/C++ programmer. The environment runs on Debian, and hence is a good place to start for all School / College students too.
As part of my investigations for my college teaching environments, I was in a situation where I needed to teach C++. And, as some of my readers know, I am compulsively obsesses with not installing any compiler, or programming environment, on my local machine. It has to run in a throwaway-able environment.
So, I looked at the default DevContainer setup that Microsoft ships as part of their images. The environment created a 2GB image on my machine. That was really not something I like working with. So, here are the things you to be more efficient, and nimble.
## Getting started
Create an empty project folder in a location of your choice on the machine. And then:
`mkdir .devcontainer`
This will create a `.devcontainer` folder inside that. The below files will go inside this folder.
## The `Dockerfile`
I used the following `Dockerfile` for the environment:
```dockerfile
FROM debian:stable-slim
RUN apt-get update \
&& apt-get install -y git g++ gcc make gdb \
&& apt-get clean
WORKDIR /root
CMD ["sleep infinity"]
```
This gets us in a good place. It has support for the tools mentioned in the install line, and generates an image the size of approximately 820MB. A far cry from the 2GB+ from the Microsoft Container repository. Plus, I have control over the linux version, and more.
## The DevContainer
The `Dockerfile` is never enough. It has to be supplemented with an appropriate `devcontainer.json` to be effective. So, here is the my version of that file.
```json
{
"name": "cpp-dev-container",
"build": {
"dockerfile": "Dockerfile"
},
"customizations": {
"vscode": {
"settings": {
"remote.downloadExtensionsLocally": true,
"telemetry.enableTelemetry": false,
"extensions.ignoreRecommendations": false,
"workbench.remoteIndicator.showExtensionRecommendations": false
},
"extensions": [
"ms-vscode.cpptools",
"kunalg.library-documentation-cpp",
"danielpinto8zz6.c-cpp-compile-run"
]
}
}
}
```
There you go. Now you are ready to `Ctrl+P` or `Cmd+P` and `Reopen in Container` .
When you open the container, there is an extension called `CompileAndRun` that will allow you to run the current C/C++ file using **the default settings**. You can also set the breakpoints.
Have fun C++ing

Problem Description
Is there a way to manually set the checkbox of the ListTable in VTable, and how to clear the selected state of all checkboxes?
## Solution
Call the interface to update the state
You can call the interface setCellCheckboxState. This interface can set the checkbox state of a cell, and is defined as follows:
```
setCellCheckboxState(col: number, row: number, checked: boolean) => void
```
Parameter description:
- col: Column number
- row: Row number
- checked: Whether checked
Example: tableInstance.setCellCheckboxState(0, 3, true) sets the Checkbox state of the cell at position (0, 3) to checked state. The demo effect after modifying the official website is as follows: https://visactor.io/vtable/demo/cell-type/checkbox
Batch update status:
For the second question about batch update, currently, there is no dedicated interface to reset the status of all checkboxes. However, you can achieve the goal of updating all checkbox statuses by resetting the data using setRecords or updating the column configuration using updateColumns.
1. Update through column configuration
Add "checked" as true or false in the column configuration to set the status of the entire column. However, if there is a field in the data records indicating the status, the data record will prevail.
2. To batch set the checkbox status by updating the records data source, it is required to explicitly specify the checkbox value fields in the records.

His father, John Shakespeare, was a successful glove-maker and alderman, while his mother, Mary Arden, belonged to a prominent local family. Shakespeare likely attended the King's New School in Stratford, where he received a rigorous education in grammar, Latin, and classical literature. In 1582, at the age of 18, **[Shakespeare](https://youtu.be/qLrvt8QfyJ4?si=CnD91zM-4zb3AMNe)** married Anne Hathaway, who was eight years older than him. The couple had three children: Susanna, born in 1583, and twins Hamnet and Judith, born in 1585. Tragically, Hamnet died at the age of 11, an event that is often speculated to have influenced Shakespeare's work.
**[Shakespeare's](https://youtu.be/qLrvt8QfyJ4?si=CnD91zM-4zb3AMNe)** career in London began in the late 1580s or early 1590s, where he joined a theatrical company known as the Lord Chamberlain's Men, later renamed the King's Men under King James I. By 1592, Shakespeare had already established himself as an actor and playwright. His early works, including comedies like "A Midsummer Night's Dream" and histories such as "Henry IV," gained him considerable acclaim.
Over the course of his career, Shakespeare wrote 39 plays, 154 sonnets, and several narrative poems. His works are renowned for their complex characters, intricate plots, and profound exploration of human nature. Notable tragedies like "Hamlet," "Othello," "King Lear," and "Macbeth" delve into themes of ambition, power, betrayal, and madness, showcasing his unparalleled ability to capture the human experience.
Shakespeare retired to Stratford around 1613 and died on April 23, 1616. His legacy endures through the timeless appeal of his works, which continue to be performed and studied worldwide, solidifying his place as a towering figure in literature and drama.

1,888,302 | 5 Key Differences to know about Regression Testing and Retesting | As you must be aware, depending on the stage of development, various types of testing are undertaken... | 0 | 2024-06-14T10:28:53 | https://dev.to/morrismoses149/5-key-differences-to-know-about-regression-testing-and-retesting-1l68 | retesting, regressiontesting, testgrid | As you must be aware, depending on the stage of development, various types of testing are undertaken during the multiple phases of the software development life cycle (SDLC). Each level of the SDLC has its own set of requirements and objectives for testing to meet.
Unit testing is followed by integration testing, system testing, system integration testing, acceptance testing, and regression testing in the testing phase.
There are many distinct sorts of tests in software testing. However, due to their likeness and apparent overlap in purposes, people often misunderstand them. Regression testing and retesting are two ideas that are frequently misunderstood. They have comparable sounds and similarities which cause confusion.
But, are they similar?
If not, then what are the differences between them?
A detailed comparison is what we need to clear these doubts between regression testing and retesting.
## What is Retesting?
The term “retest” refers to the second round of testing. It makes no difference what the reason is. You retest when you repeat a test. You could retest the functionality of the current version. Or a bug fix, functionality from a prior version, a test case you just ran, and so on.
If you’re still perplexed as to why then consider the following arguments:
●Yesterday, you did a test and discovered a flaw. You want to make sure the steps and the defect are repeatable. As a result, you retest.
●You performed a test. But, you weren’t paying attention to it. You want to double-check, so you retest.
Retesting is the process of repeating a test for any specific reason. It’s one of those words that means what it says.
## What is Regression Testing?
Regression Testing is one of the types of black-box testing. It ensures that any changes or additions to the existing code base do not negatively influence features that have already been developed and tested.
Regression testing ensures that the application continues to function as expected after a modification. Regression testing falls into two types called smoke and sanity testing. When performing regression testing, you run both functional and non-functional tests. A new module is never subjected to regression testing.
Read also: [Regression Testing: Complete Guide](https://testgrid.io/blog/regression-testing-complete-guide/)
## What Does Regression Testing Aim to Achieve?
The whole point of regression testing is to make sure that new code changes do not negatively influence the application’s previously created and tested functions.
### When is it Necessary to Conduct Regression Testing?
- Testers perform Regression testing in any of the following situations:
- When a client submits a change request (CR), the code base undergoes alteration.
- In cases, where the testing environment undergoes a change.
- When you move the back-end code to a new platform.
- During the testing process, the developer discovers a critical bug and rectifies it.
- An existing software gets a new feature.
- The developers have addressed the essential concerns about performance difficulties and crashes.
- Fixes have been added to the patch.
- For a better user experience, the application’s UI underwent modifications.
### Explaining the Difference Between Regression testing and Retesting
To demonstrate the distinction between regression testing and retesting, consider the following example:
Consider the following two possibilities.
Case 1: Login Page – Login Button that is not working (Bug)
Case 2: Login Page – Added a checkbox to “Stay signed in” (New feature)
In Case 1, the login button isn’t working. Therefore the tester files a bug report. After the repair of the bug, testers check to see if the Login button is functioning as expected.
In Case 2, the tester evaluates the new feature to check it works as intended (Stay signed in).
Retesting applies to Case 1. Here, the tester retests the bug discovered in the previous build by following the steps outlined in the bug report.
In Case 1, the tester also does regression testing on features linked to the login button.
Case 2 falls within the category of regression testing. Here, you test the new feature (Stay signed in) as well as the associated functionalities. Regression Testing is the process of testing relevant functionalities while also testing new features.
Another Example
Consider the following scenario:
An application under test contains three modules: administration, Purchase, and finance. The Purchase module is dependent on the Finance module. Suppose a tester discovered and reported an issue in the Purchase module. Once the tested rectify the bug, he must perform Retesting. This will ensure the resolving of the bug related to Purchase. Regression Testing tests the Finance module that depends on the Purchase module.
## Comparison between Regression Testing and Retesting
### What do they have in common?
- Validation and Black box testing methodologies are both based on repetition.
- Both automated and manual test cases undergo retesting and regression testing.
### What makes them different?
- Any test – current or prior version functionality targeted – can benefit from retesting. The functionality of previous versions is the focus of regression.
- There is no requirement for retesting if there has been a change. Change is the focus of regression.
- On failed test cases, testers perform retesting, whereas they perform regression testing on passed test cases.
- Retesting ensures the rectification of the original error, whereas regression Testing ensures that there have been no unanticipated side effects.
- Regression testing has a lesser priority than retesting. Testers conduct regression testing parallel to retesting.
- Due to the ambiguity, we are unable to automate the test cases for Retesting. On the other hand, you can automate regression testing.
- Regression testing is generic testing. Retesting is a planned test. Regression is a broad topic with a variety of subtypes. Automation is also a good fit for regression testing. If your team is spending a bunch of time running the same regression test cases over and over, it may be time to automate them. The examples and differences mentioned above give us a better understanding of the differences between Regression testing and Retesting.

Hey there! Have you ever wondered how your messages stay private when you chat with your friends online? How does your personal information stay safe from prying eyes? The answer lies in something called end-to-end encryption. One popular method for achieving this is RSA encryption. Let’s dive into what this means in a way that’s easy to understan](https://finrock.io/)
What is End-to-End Encryption?
[Imagine you want to send a secret note to your friend. You write it down, put it in a locked box, and give the key to your friend so only they can open it. End-to-end encryption is just like that locked box, but for digital messages. It ensures that only you and the person you’re communicating with can read your messages](https://finrock.io/)
What is RSA Encryption?
RSA encryption is a type of cryptography that helps in locking and unlocking these digital. boxes. It’s named after its inventors: Rivest, Shamir, and Adleman
How Does RSA Work?
Keys: RSA uses two keys — a public key and a private key.
oPublic Key: This is shared with everyone. It’s like the lock on the box.
oPrivate Key: This is kept secret. It’s like the key that can unlock the box
Step-by-Step Example
Meet Alice and Bob:
o Alice wants to send a secret message to Bob.
o Bob has a public key (which he shares with everyone) and a private key
(which he keeps secret).
2. Alice Encrypts the Message
o Alice writes her message, “Hello Bob!”
o She uses Bob’s public key to encrypt the message.
o The encrypted message looks like a bunch of random letters and numbers.
3. Bob Decrypts the Message:
o Bob receives the encrypted message.
o He uses his private key to decrypt it.
o Bob can now read the message, “Hello Bob!
Here’s a simple animation to visualize the process
RSA encryption process.
Why is RSA Important?
Security: It keeps your messages and data safe from hackers.
Privacy: Only the intended recipient can read the message.
Authentication: It can also be used to verify that the sender is who they say they are.
Fun Facts About RSA
Big Numbers: RSA encryption relies on very large prime numbers, making it extremely difficult to crack.
. Daily Use: It’s used in many everyday applications like online banking, secure emails, and even some messaging apps.
. History: It was first introduced in 1977 and remains one of the most widely used encryption methods today.
Conclusion
End-to-end encryption using RSA ensures your digital life stays private and secure. By using public and private keys, it creates a secure environment for communication and data transfer. Next time you send a message, you can feel confident knowing that RSA encryption is working behind the scenes to keep it safe!

1,888,300 | How to implement dimension drill-down function when using VTable pivot table component? | Problem Description Does the VTable pivot table support drill-down interaction on the... | 0 | 2024-06-14T10:28:19 | https://dev.to/fangsmile/how-to-implement-dimension-drill-down-function-when-using-vtable-pivot-table-component-49pk | visactor, vtable, webdev, visiualization | ## Problem Description
Does the VTable pivot table support drill-down interaction on the front end?
## Solution
Configuring this will give you an icon and listen for events (https://visactor.io/vtable/api/events#DRILLMENU_CLICK). Call the interface updateOption to update the full configuration after obtaining new data.
## Code Example
You can refer to the official demo: https://visactor.io/vtable/demo/data-analysis/pivot-analysis-table-drill.
Key configuration for drillDown:
```
const option = {
records: data,
rows: [
{
dimensionKey: 'Category',
title: 'Category',
drillDown: true,
headerStyle: {
textStick: true
},
width: 'auto'
}
],
columns: [
{
dimensionKey: 'Region',
title: 'Region',
headerStyle: {
textStick: true
},
width: 'auto'
}
],
indicators: ...
};
```
After configuration, the drill-down icon is displayed, and the click event of the icon drillmenu_click is listened. In the event processing logic, updateOption is called to update the configuration, and the configured drill-down icon changes to the drill-up icon drillUp.
```
tableInstance.on('drillmenu_click', args => {
if (args.drillDown) {
if (args.dimensionKey === 'Category') {
tableInstance.updateOption({
records: newData,
rows: [
{
dimensionKey: 'Category',
title: 'Category',
drillUp: true,
headerStyle: {
textStick: true
},
width: 'auto'
},
{
dimensionKey: 'Sub-Category',
title: 'Sub-Catogery',
headerStyle: {
textStick: true
},
width: 'auto'
}
],
columns: ...,
indicators: ...
});
}
}
```

As someone who is part of the LGBTIQA+ community, this month is both great... | 0 | 2024-06-14T10:27:00 | https://eevis.codes/blog/2024-06-14/pride-in-your-app-trying-out-graphql-on-android/ | graphql, android, mobile, programming | It's Pride month, y'all! As someone who is part of the LGBTIQA+ community, this month is both great and stressful at the same time. You never know what some people come up with - somehow, this month draws some really nasty people out. And with the rise of far-right in Europe... I'm not even going to get started.
I have wanted to try out GraphQL with Android for quite a while, and when I came across this [Pride Flag API][1], I thought that now was the time. What a great way to celebrate Pride by trying out the API (and GraphQL) and writing a blog post about it!
A bit of background about me and GraphQL: I started my public speaking career talking about GraphQL (and JavaScript. That's my dark secret.). It was fun, and I liked it a lot. Of course, there are always pros and cons when thinking about using any technology, but nevertheless, I liked it a lot. I even got this "Ask me about GraphQL" T-shirt from one meetup, and that was probably the coolest t-shirt I've gotten.
When I switched to Android, there were no use cases for me to learn how to integrate GraphQL with Android. So, I've wanted to try it for a while now, and I'm glad I found a great way to test it. Let's get started!
## GraphQL
If you've never heard the word GraphQL, it's a query language and an alternative way of building APIs in the form of graphs - hence the name.
GraphQL APIs let you ask for what you need - and only that. So, compared to REST APIs, which always return everything, GraphQL APIs return only the values you've asked for. And as it's graph-based, you can get nested data with one query. An example would be authors, their books, and the characters in the books - with REST API, you'd need to make three requests (depending on the API, naturally).
GraphQL offers three actions: querying, mutating, or subscribing to data. Compared to REST, querying matches the `GET` requests, mutating matches all the others that mutate data, and subscribing is a two-way street - like, for example, WebSockets.
In the context of this blog post, we're going to _query_ data. To learn more about the operations available and GraphQL in general, head over to [GraphQL's documentation][3].
To use GraphQL, we're going to use [Apollo Kotlin][4] (formerly Apollo Android). The library is type-safe and compatible with Kotlin Multiplatform.
## Dependencies and Getting the Schema
To get started with Apollo Kotlin, we need to add some dependencies to the project:
```kotlin
// project-level build.gradle.kts
plugins {
id("com.apollographql.apollo3").version("3.8.4")
}
```
and
```kotlin
// module-level build.gradle.kts
dependencies {
implementation("com.apollographql.apollo3:apollo-runtime:3.8.4")
}
```
Note that the version numbers for these packages must be the same.
In addition to dependencies, we need to add a package name addition task for the generated models:
```kotlin
// module-level build.gradle.kts
apollo {
service("service") {
packageName.set("com.example")
}
}
```
With many projects, syncing gradle files would happen right here. However, this project is different; we still need the schema for the GraphQL queries. There are several options, but with an external API, downloading the schema with introspection is the easiest. We need to save the schema to `src/main/graphql`, and in the case of this small project, we do it with the following command:
```shell
./gradlew :app:downloadApolloSchema --endpoint='https://pride.dev/api/graphql' --schema=app/src/main/graphql/schema.graphqls
```
Once we have the schema, it's time to sync the gradle files and continue to querying the data.
## Querying Data
For this small app, we want to read the data - so, in GraphQL's terms, we want to query it. We don't need every property for the flags, so we define a query with just what we need:
```graphql
query FlagQuery {
allFlags {
name
year
svgUrl
}
}
```
With Apollo Kotlin, all queries need to be named queries. You'll run into an error if you have an unnamed query - trust me, I know.
This query gets all the available flags from the API. We need the flag's name, year, and SVG URL, so we write those properties in our query.
To add the query to the Android project, we first need to create a file in the `src/main/` folder, which is the very same folder where the schema lives. Let's call the file `FlagQuery.graphql` and add the query there. Apollo generates the model for the query through an automated task that runs when the app is built. So, let's build the app, and then query's model will be available.
At this point, I want to remind you to add the internet permission to `AndroidManifest`. If you don't, well, the following steps will become more complicated. Trust me, I know.
Here's a reminder on what to add, so you don't need to use a search engine to find it, like I did:
``` xml
// AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
```
Okay, now we have the query, but how do we connect it to the UI? The answer is a GraphQL client, which we can use to query the data. I'm making things straightforward for the purposes of this demo, so we only define a GraphQL client and then query the data in a view model. In a production-grade app, you'd probably have a more layered architecture.
First, we define the client:
```kotlin
// GraphQLClient.kt
const val API_ENDPOINT = "https://pride.dev/api/graphql"
val apolloClient = ApolloClient.Builder()
.serverUrl(API_ENDPOINT)
.build()
```
In the view model, we first define a state to use in the UI:
```kotlin
// FlagsViewModel.kt
data class FlagsUiState(
val loading: Boolean = true,
val flags: List<FlagQuery.AllFlag> = emptyList(),
val currentFlag: FlagQuery.AllFlag? = null,
)
class FlagsViewModel : ViewModel() {
private var _state = MutableStateFlow(FlagsUiState())
val state = _state.asStateFlow()
...
}
```
We want to store all the flags we get from the API and display the current flag on a detail page, so we have properties for `flags` and `currentFlag` in the state. The type (`FlagQuery.AllFlag`) for both is generated by Apollo Kotlin.
To query all the flags, let's define a function inside the view model:
```kotlin
// FlagsViewModel.kt
suspend fun getFlags() {
val flagsQuery = apolloClient
.query(FlagQuery())
.execute()
_state.update { currentState ->
currentState.copy(
loading = false,
flags = flagsQuery.data?.allFlags ?: emptyList(),
)
}
}
```
So, to get the flags, we need a suspend function, inside which we call the `apolloClient.query(...).execute()` with the `FlagQuery` we defined previously. On success, it returns data in the `data` property, which we can then use to update the state with.
I mentioned that we also want to store the current flag in the state. Setting it is a straightforward function without any GraphQL-magic:
```kotlin
// FlagsViewModel.kt
fun setFlag(flag: FlagQuery.AllFlag) {
_state.update {
it.copy(
currentFlag = flag,
)
}
}
```
## A Couple of Words About the UI
On the UI side, we're doing pretty simple things: displaying a list of the flags and then navigating to a detail view. As it's not related to GraphQL, meaning it's just passing data as state, it's out of the scope of this blog post.
Here's a video of how the experience looks like:
<video controls class="portrait-video">
<source src="//videos.ctfassets.net/mpqufjsy02zr/5W91AkqqUwf0yF3ZTPvlxe/ef58576b6e971396b92be4dc6c040e88/flag-explorer.webm" type="video/webm" />
</video>
If you're interested in checking the UI code out, head over to the repository: [Flag Explorer][2]
## Wrapping Up
In this blog post, we discussed GraphQL and how to use it in an Android project. As an example, we built a small app that fetches Pride flags from the [Pride Flag API][1].
In the end, adding GraphQL to the project was surprisingly straightforward. For some reason, I had thought it'd be much more complicated. As mentioned in the beginning, I have warm feelings towards GraphQL, so it'd be great to use it in some real projects. We'll see what the future brings!
What do you think of GraphQL? Have you tried it out?

The mini graph in the product uses VTable, but the effect of generating the mini graph with data is that the users feel the distance between adjacent line segments is too close. How to adjust this spacing?
## Solution
First, it is necessary to clarify that the width and height of a cell include two parts: the padding margin and the content. The padding margin in the VTable is set to [10, 16, 10, 16] by default, and the row height of the VTable is 40px by default, with the top and bottom padding margins taking up 20px. Therefore, the height of the content is reduced to 20px.
The top and bottom padding margins take up 20px, so the minimum distance between two adjacent sparklines charts is also 20px. In other words, the minimum distance between two adjacent sparklines charts is determined by the padding margin. In the official example, padding margin is adjusted to 20, and it is found that the line curve becomes a straight line after the adjustment. This is because the 40px row height is occupied by the padding margin, leaving no space for the line chart to stretch.
So in this case, we need to increase the row height accordingly. The effect of setting defaultRowHeight to 60 is as follows:
## Code Example
```
const records = [
{
'lineData':[50,20,20,40,60,50,70],
'lineData2':[{x:1,y:1500},{x:2,y:1480},{x:3,y:1520},{x:4,y:1550},{x:5,y:1600}],

}
];

1,888,260 | Defining Custom Exception Classes | You can define a custom exception class by extending the java.lang.Exception class. Java provides... | 0 | 2024-06-14T10:20:27 | https://dev.to/paulike/defining-custom-exception-classes-pgm | java, programming, learning, beginners | You can define a custom exception class by extending the **java.lang.Exception** class. Java provides quite a few exception classes. Use them whenever possible instead of defining your own exception classes. However, if you run into a problem that cannot be adequately described by the predefined exception classes, you can create your own exception class, derived from **Exception** or from a subclass of **Exception**, such as **IOException**.
In [here](https://dev.to/paulike/more-on-exception-handling-529c), CircleWithException.java, the **setRadius** method throws an exception if the radius is negative. Suppose you wish to pass the radius to the handler. In that case, you can define a custom exception class, as shown in the program below.
This custom exception class extends **java.lang.Exception** (line 1). The **Exception** class extends **java.lang.Throwable**. All the methods (e.g., **getMessage()**, **toString()**, and **printStackTrace()**) in **Exception** are inherited from **Throwable**. The **Exception** class contains four constructors. Among them, the following two constructors are often used:
Line 6 invokes the superclass’s constructor with a message. This message will be set in the exception object and can be obtained by invoking **getMessage()** on the object. Most exception classes in the Java API contain two constructors: a no-arg constructor and a constructor with a message parameter.
To create an **InvalidRadiusException**, you have to pass a radius. Therefore, the **setRadius** method in CircleWithException.java can be modified as shown in program below.
```
package demo;
public class TestCircleWithCustomException {
public static void main(String[] args) {
try {
new CircleWithCustomException(5);
new CircleWithCustomException(-5);
new CircleWithCustomException(0);
}
catch(InvalidRadiusException ex) {
System.out.println(ex);
}
System.out.println("Number of objects created: " + CircleWithCustomException.getNumberOfObjects());
}
}
class CircleWithCustomException{
/** The radius of the circle */
private double radius;
/** The number of objects created */
private static int numberOfObjects = 0;
/** Construct a circle with radius 1 */
public CircleWithCustomException() throws InvalidRadiusException{
this(1.0);
}
/** Construct a circle with a specified radius */
public CircleWithCustomException(double newRadius) throws InvalidRadiusException {
setRadius(newRadius);
numberOfObjects++;
}
/** Return radius */
public double getRadius() {
return radius;
}
/** Set a new radius */
public void setRadius(double newRadius) throws InvalidRadiusException{
if(newRadius >= 0)
radius = newRadius;
else
throw new InvalidRadiusException(newRadius);
}
/** return numberOfObjects */
public static int getNumberOfObjects() {
return numberOfObjects;
}
/** Return the area of this circle */
public double findArea() {
return radius * radius * 3.14159;
}
}
```
`InvalidRadiusException: Invalid radius -5.0
Number of objects created: 1
`
The **setRadius** method in **CircleWithCustomException** throws an **InvalidRadiusException** when radius is negative (line 48). Since **InvalidRadiusException** is a checked exception, the **setRadius** method must declare it in the method header (line 44). Since the constructors for **CircleWithCustomException** invoke the **setRadius** method to a set a new radius and it may throw an **InvalidRadiusException**, the constructors are declared to throw **InvalidRadiusException** (lines 28, 33).
Invoking **new CircleWithCustomException(-5)** (line 8) throws an **InvalidRadiusException**, which is caught by the handler. The handler displays the radius in the exception object **ex**.
Can you define a custom exception class by extending **RuntimeException**? Yes, but it is not a good way to go, because it makes your custom exception unchecked. It is better to make a custom exception checked, so that the compiler can force these exceptions to be caught in your program. | paulike |

1,882,036 | CS50 - Week 2 | Kompilyatsiya qilish Shifrlash - bu oddiy matnni begona ko'zlardan yashirish jarayoni.... | 0 | 2024-06-14T10:19:09 | https://dev.to/udilbar/cs50-week-2-23cf | cs50, programming, c, learning | ## Kompilyatsiya qilish
**Shifrlash** - bu oddiy matnni begona ko'zlardan yashirish jarayoni. **Deshifrlash** esa, shifrlangan matnni inson o'qiy oladigan shaklga qaytarishdir.
Shifrlangan matn quyidagicha ko'rinishi mumkin:
**Kompilyator** - dastlabki kodni kompyuter tushunadigan mashina kodiga aylantiradigan maxsus kompyuter dasturi.
Bizga `hello.c` faylida quyidagi berilgan bo'lsin:
```c
#include <stdio.h>
int main(void)
{
printf("hello, world\n");
}
```
Kompilyator yuqoridagi kodni olib, quyidagi mashina kodiga aylantiradi:
**VS Code** - to'liq nomi **Visual Studio Code**, bu _Microsoft_ tomonidan ishlab chiqilgan bepul va ochiq manbali kod muharriri hisoblanadi. CS50 kursi talabalari uchun [cs50.dev](https://cs50.dev) saytida _VS Code_ kod muharriri sozlangan bo'lib, unda kompilyator sifatida `clang` ni ishlatadi.
**clang** – bu C, C++, va boshqa dasturlash tillari uchun mo‘ljallangan yuqori samarali va tezkor kompilyator hisoblanadi.
Rasmda chap tomonda fayllarimizni topishimiz mumkin. Shuningdek, o'rtada matn muharriri joylashgan. O'ng tomon pastda **buyruqlar qatori interfeysi** (_CLI_) yoki **terminal oynasi** deb ataladigan soha mavjud bo'lib, bu yerdan kompyuterga buyruqlarni yuborishimiz mumkin.
`make hello` buyrug'ini _VS Code_ kod muharrining terminal oynasida kiritadigan bo'lsak, u `clang` ni chaqiradi va `hello.c` faylimizni kompilyatsiya qiladi. Dasturimizni `./hello` buyrug'i orqali ishga tushura olamiz.
Kompilyatsiya qilish bir nechta qadamlarni o'z ichiga oladi:
- _oldindan qayta ishlash_ (_preprocessing_) - bu koddagi sarlavha fayllari (masalan, `#include <stdio.h>`) faylimizga nusxalanib, joylashtiriladigan bosqichdir:
```c
int printf(string format, ...);
int main(void)
{
printf("hello, world\n");
}
```
- _kompilyatsiya qilish_ (_compiling_) - bu dasturni assembler kodiga aylantirishdir:
- _yig'ish_ (_assembling_) - kompilyatorning assembler kodini mashina kodiga aylantirish:
- _bog'lash_ (_linking_) - bu bosqichda kodimizga kiritilgan kutubxonalar kodlari ham mashina kodiga aylantiriladi va birlashtiriladi:
---
## "Debug" qilish
Har kim ham dasturlash jarayonida xatolar qiladi. Quyidagi ataylab xato bilan yozilgan `buggy.c` faylini ko'rib chiqsak:
```c
#include <stdio.h>
int main(void)
{
for (int i = 0; i <= 3; i++)
{
printf("#\n");
}
}
```
Ushbu kodni ishga tushirganimizda, ekranga uchta belgi o'rniga to'rtta belgi ekranga chiqadi. `printf` funksiyasi yordamida dasturimizning qayerida xato qilganimizni qanday topishni ko'rib chiqamiz:
```c
#include <stdio.h>
int main(void)
{
for (int i = 0; i <= 3; i++)
{
printf("i - bu %i\n", i);
}
}
```
Yuqoridagi kodimizni ishga tushirsak, terminalda quyidagi matnlar paydo bo'ladi:
Buni ko'rib, kodni quyidagicha to'g'rilash kerakligini tushunamiz:
```c
#include <stdio.h>
int main(void)
{
for (int i = 0; i < 3; i++)
{
printf("#\n");
}
}
```
Ya'ni, `<=` (_kichik yoki teng_) belgisini `<` (_kichik_) belgisiga o'zgartirdik.
Dasturdagi xatolarni to'g'rilashning ikkinchi vositasi "**debugger**" deb atalib, u dasturchilar tomonidan koddagi xatolarni kuzatishda yordam berish uchun yaratilgan dasturiy vositadir.
_VS Code_ da oldindan sozlangan _debugger_ mavjud. Ushbu debuggerdan foydalanish uchun quyidagi bosqichlarni bajaramiz:
- "**Breakpoint**" _qo'yish_ - kod satrining chap tomoniga bosganimizda qizil nuqta (_to'xtash belgisi_) paydo bo'ladi va u kompilyatorga ushbu kod qismida to'xtab, nima sodir bo'layotganini ko'rib chiqishimiz mumkinligini bildiradi.
- _Debuggerni ishga tushirish_ - terminalda `debug50 ./buggy` buyrug'ini bersak debugger ishga tushadi va breakpoint qo'yilgan satrda kod bajarilishi to'xtaydi.
- _Kodni tahlil qilish_ - barcha mahalliy o'zgaruvchilar chap yuqori burchakda ko'rsatiladi. Ekranning yuqorisida joylashgan "**step over**" tugmasini bosib, kodimizni birma-bir tekshirib chiqamiz. Bunda `i` o'zgaruvchisining qiymati qanday oshayotganini ko'rishimiz mumkin bo'ladi.
Debugger bizga qayerda xato borligini ko'rsatmasa ham, kodning qanday ishlashini asta-sekin ko'rib chiqishimizga yordam beradi.
---
## Massivlar
Kompyuterimiz ichida mavjud bo'lgan xotira miqdori cheklangan.
Kompyuter xotirasida ma'lum turdagi ma'lumotlar qanday saqlanishini tasavvur qilaylik. Masalan, `char` turi faqat 1 bayt xotira talab qiladi va u quyidagicha ko'rinishi mumkin:
Shuningdek, 4 bayt xotira talab qiladigan `int` turi esa quyidagicha ko'rinishi mumkin:
**Massivlar** - ma'lumotlarni xotirada ketma-ket saqlash usulidir. Shuning uchun bu ma'lumotlarni osonlik bilan olish mumkin.
`int scores[3]` - bu kompilyatorga `int` turidagi uchta butun sonlarni saqlash uchun ketma-ket uchta joy ajratish buyrug'idir. Keling, ushbu ballarning o'rta arifmetigini topuvchi dastur yaratamiz:
```c
#include <stdio.h>
int main(void)
{
// Ballar qiymatini kiritish
int scores[3];
scores[0] = 72;
scores[1] = 73;
scores[2] = 33;
// O'rta arifmetigini hisoblash va ekranga chiqarish
printf("Average: %f\n", (scores[0] + scores[1] + scores[2]) / 3.0);
}
```
`scores[0]` - massivning 0-indexsida turgan qiymatini kompyuter xotirasidan ko'rib chiqadi. Keling, `scores` massivi xotirada qanday joylashganini ko'ramiz:
Keling, yuqoridagi kodimizni abstraktlaymiz:
```c
#include <cs50.h>
#include <stdio.h>
// O'zgarmas butun son
const int N = 3;
// Funksiya prototipi
float average(int length, int array[]);
int main(void)
{
// Ballar qiymatini kiritish
int scores[N];
for (int i = 0; i < N; i++)
{
scores[i] = get_int("Score: ");
}
// O'rta arifmetikni ekranga chiqarish
printf("Average: %f\n", average(N, scores));
}
float average(int length, int array[])
{
// O'rta arifmetikni hisoblash
int sum = 0;
for (int i = 0; i < length; i++)
{
sum += array[i];
}
return sum / (float) length;
}
```
`for` sikli orqali `scores[i]` yordamida massiv elementlariga qiymat kiritamiz. O'zgarmas butun son `N` e'lon qilingan. Shuningdek, `average` funksiyasi e'lon qilingan va u `int array[]` qabul qiladi, ya'ni kompilyator massivni ushbu funksiyaga o'tkazadi.
Demak, massivlar nafaqat konteyner bo'lishi, shu bilan birga ular funksiyalar orasida o'tkazilishi mumkin ekan.
---
## String
**String** - bu `char` turidagi o'zgaruvchilar massividir, ya'ni belgilar massivi. Bunda u ma'lum belgi bilan boshlanib, satr tugaganini bildirish uchun maxsus `NUL` belgisi bilan tugaydi:
Keling, `char` turidagi o'zgaruvchilarni ekranga chiqaruvchi dastur yozamiz:
```c
#include <stdio.h>
int main(void)
{
char c1 = 'H';
char c2 = 'I';
char c3 = '!';
printf("%c%c%c\n", c1, c2, c3);
}
```
Agar `%c` format kodini `%i` bilan almashtirsak, berilgan `char` turidagi o'zgaruvchilarning **ASCII** kodlari chop etiladi:
```c
#include <stdio.h>
int main(void)
{
char c1 = 'H';
char c2 = 'I';
char c3 = '!';
printf("%i %i %i\n", c1, c2, c3);
}
```
`string` qanday ishlashini yaxshiroq tushunish uchun kodimizni quyidagicha o'zgartiramiz:
```c
#include <cs50.h>
#include <stdio.h>
int main(void)
{
string s = "HI!";
printf("%c%c%c\n", s[0], s[1], s[2]);
}
```
Bunda `string` turidagi `s` o'zgaruvchimiz aslida massiv bo'lganligi sababli, 0-, 1- va 2-indeksdagi qiymatlarni chaqirishimiz mumkin.
Oldingidek, `%c` format kodini `%i` bilan almashtirishimiz mumkin:
```c
#include <cs50.h>
#include <stdio.h>
int main(void)
{
string s = "HI!";
printf("%i %i %i %i\n", s[0], s[1], s[2], s[3]);
}
```
Bunda `string` turidagi `s` o'zgaruvchisi belgilarining **ASCII** kodlari hamda `NUL` belgisi ekranga chiqadi.
## String uzunligi
C tilida massivning uzunligini aniqlash muammosi mavjud. `string` ham aslida belgilar massividir. Keling `string` turidagi o'zgaruvchi uzunligini aniqlaymiz:
```c
#include <cs50.h>
#include <stdio.h>
int string_length(string s);
int main(void)
{
// Foydalanuvchining ismini so'rash
string name = get_string("Name: ");
int length = string_length(name);
printf("%i\n", length);
}
int string_length(string s)
{
// Belgilar sonini NUL belgisigacha hisoblash
int n = 0;
while (s[n] != '\0')
{
n++;
}
return n;
}
```
Bunda `string` turidagi `name` o'zgaruvchisining uzunligi `NUL` belgisi topilgunga qadar hisoblanyabdi.
Bu dasturlashda juda keng tarqalgan muammo bo'lganligi sababli, boshqa dasturchilar `string` uzunligini hisoblashni osonlashtirish uchun `string.h` kutubxonasida tayyor `strlen` funksiyasini yaratganlar va biz uni shunchaki chaqirib ishlatishimiz mumkin:
```c
#include <cs50.h>
#include <stdio.h>
#include <string.h>
int main(void)
{
// Foydalanuvchining ismini so'rash
string name = get_string("Name: ");
int length = strlen(name);
printf("%i\n", length);
}
```
`string.h` kutubxonasi kodning yuqori qismida e'lon qilingan va foydalanuvchi kiritgan `name` o'zgaruvchisining uzunligini hisoblash uchun tayyor `strlen` funksiyasidan foydalanilyabdi.

1,888,236 | Top 11 Security Measures for Protecting Your Storage System Server | Server security requires ongoing diligence, as threats are constantly evolving in sophistication... | 0 | 2024-06-14T10:13:26 | https://dev.to/adelenoble/top-11-security-measures-for-protecting-your-storage-system-server-4d9m | Server security requires ongoing diligence, as threats are constantly evolving in sophistication while new vulnerabilities are regularly uncovered. It's a full-time job, just keeping your defenses updated and strengthened.
The challenge of shoring up your virtual walls and gates has never been greater. Yet turning a blind eye to the risks of your [**data center**](https://www.lenovo.com/ca/en/servers-storage/servers/) is not an option either, as the potential damage from an infiltration ranges from mere annoyance to complete business disruption. In this environment, a proactive stance and commitment to security best practices are the only viable strategies.
Let’s scroll down and explore 11 measures you can implement to strengthen your server's defenses.
### 1. Control Who Has Access — And Revoke It When Needed
Limiting who can log into your system server limits who can potentially do harm. Be discriminating about granting access; only provide it to those who genuinely require it. And remember, people's needs change. Review accounts regularly and remove any that are no longer necessary. Tight access controls are your first line of protection.
### 2. Require Strong Passwords — And Change Them Often
Passwords are your enterprise server's first password of entry. So make sure to demand robust, unique passwords that would be difficult for attackers to guess or crack. Aim for long passcodes with a mix of letters, numbers, and symbols changed every 30–90 days. Also, enable two-factor authentication for added verification when logging in. Strong, rotating passwords significantly heighten the security bar.
### 3. Install And Regularly Update Antivirus Software
Outdated antivirus leaves gaps that viruses and malware can seep through to infect your server.
- Install antivirus software from a reputable vendor and keep it up-to-date. New viruses and malware are emerging all the time, so your antivirus needs the latest definition files and program updates to recognize and defend against the latest threats.
- Configure regular scans of your compact server's files and storage locations. Daily quick scans plus a thorough weekly scan is a good baseline schedule. Scans identify any malware that has somehow slipped past your defenses.
- Enable real-time scanning and monitoring. With real-time protection switched on, any new or transferred files are scanned on the fly as they are accessed. This helps catch viruses before they can do damage.
- Review scan reports and quarantined files. Your antivirus should provide details of any issues detected. Inspecting scan logs helps ensure that no problems slip by unnoticed and that quarantined files are indeed malicious and don't belong on your server.
- Consider additional layers, like malware sandboxes. New zero-day threats may evade signature-based defenses. Using sandboxes and behavioral analysis adds an extra screening layer to identify suspicious files warranting further inspection.
Research updates to your antivirus vendor's offerings. Sign up for security bulletins so you learn of any important new features or enhanced protection layers to keep your antivirus deployment optimized over time. Multiple layers of antivirus protection are recommended, given today's evolving threats.
### 4. Enable Firewall Services
A firewall acts as a filter between your high-end server and the internet, blocking unauthorized access attempts. Make sure your server's firewall is switched on, configured securely, and being actively maintained. A firewall is a basic yet important part of a multi-layered security strategy.
### 5. Patch Operating Systems And Applications Promptly
Failure to promptly patch security holes is one of the biggest blunders organizations make. Yet regular updates are so vital—they fix vulnerabilities that malicious actors are eager to exploit. Configure your server to automatically install critical updates, or at least check for them weekly and install within 30 days. Delaying patches leaves windows of opportunity for intruders.
### 6. Monitor Logins And Login Attempts
Reviewing login records provides visibility into who is accessing your server and from where. It also shines a light on suspicious behavior like multiple failed login tries, which could indicate a brute force attack in progress. Ensure your servers for enterprise are configured to log these events comprehensively so you can monitor for anomalies or traces of infiltration. Timely detection aids in a faster response.
### 7. Back Up Regularly And Test Restores
Even the most secure of systems can face hardware failure or accidental data deletion. Ensuring you can recover quickly from such incidents is critical. Set up a [backup solution](https://www.lenovo.com/ca/en/servers-storage/solutions/backup-disaster-recovery/) and schedule that backs up your system server's data, applications and configurations to a separate location at least weekly. Then periodically test restores from backups to validate their integrity and your restoration procedures. Reliable backups are a lifesaver should trouble strike.
### 8. Consider Multifactor Authentication
Gone are the days when a username and password sufficed. Adding an extra layer of verification, like a one-time code tied to a separate device, increases security significantly. Look into multifactor authentication solutions your server supports and how you can implement them. The small bit of extra hassle deters the vast majority of would-be intruders.
### 9. Use Caution With Remote Access
While remote access enables flexibility, it also widens your attack surface. Make sure your server's remote access capabilities have strong authentication and all related software components are fully patched. Closely monitor logs for anomalies. And avoid using remote access for admin-level functions if possible; on-site access is most secure when you can manage directly. Remotely connecting requires special care.
### 10. Disable Unneeded Services
The more open services running, the greater number of avenues exist for intruders to try infiltrating. Review your enterprise server's services, identify any not explicitly required, and disable them to minimize accessible points of entry. A smaller attack surface makes your system that much harder to breach.
### 11. Consider Network Segregation
Separating networks by function, like keeping servers with sensitive data on their own closed-off subnet, is a wise security tactic. Should one segment be compromised, others will remain unscathed. Consult with an IT expert to evaluate your network setup and determine how further segregation could strengthen your defenses in depth. Compartmentalization is key.
## In Summary
A holistic, layered approach to server security is needed given today's sophisticated threats. Implementing these 11 measures in an ongoing manner will serve to better safeguard your data and systems from the ever-evolving risk of intrusion and attack. Maintaining security requires vigilance, but following best practices like these helps tilt the odds in your favor. Your proactive efforts will be repaid for the protection of your valuable server resources. | adelenoble | |

When I started my **Engineering Management & Product Management** career (yes both were one and the same as the start-ups I worked at!) it was quite difficult to find learning material that was both free and not just telling you to get a degree (real helpful...).
I found an amazing book [An Elegant Puzzle - Systems of Engineering Management](https://www.amazon.co.uk/Elegant-Puzzle-Systems-Engineering-Management/dp/1732265186/ref=sr_1_1?crid=21CJ4HVXE9Z5B&dib=eyJ2IjoiMSJ9.-hFMl_9aGtJ_46DkQzhsoUc39Tca-ni5Ki0ixDDkmCqE10JqdKtMwZlgS6ZXCGkATJFTRaeLQ_RzeEWvgOD34bN7olk95VSUBkM_oaV0VVY.5nT9r9sTZjlNaWLKKRbsk-8unLQoZO1IkIknLGex17A&dib_tag=se&keywords=an+elegant+puzzle+systems+of+engineering+management&qid=1718358911&sprefix=an+eleg%2Caps%2C94&sr=8-1) that really lit a fire under my abilities as an Engineering Manager and gave me a look into the systems of Product Management such as the iterative process to problem discovery and execution.
Once I got into a Product Manager role, most of my learning was "on the job", which proved difficult at times. I would often find myself questioning whether a certain task was actually the job of a Product Manager or had it just been forced on me? I eventually pieced together a pretty good network of systems that helped me navigate the various stages of Product Management:
- Development
- Introduction
- Growth
- Maturity
- Decline
## Stepping Away From Product Management
Due to personal ambitions and no longer having any desire to work with the politics and bureaucracy of fast-paced tech startups, I ended up leaving my EM/PM career in Defence Tech and found Developer Advocacy, which luckily takes everything that I loved about my former role, with none of the headaches!
I'm lucky enough now to be the Developer Advocate for [Roadmap.sh](https://roadmap.sh) which recently hit 1.04m registered users! 🎉
I'm also now in the perfect position to right the wrongs of the lack of a free, transparent, and thorough Product Manager learning resource (the aforementioned book only covered a _very_ small element of Product Management for when you need to cross-contribute as an EM), so I wrote a Product Manager roadmap on roadmap.sh!
[Roadmap.sh Product Manager Roadmap](https://roadmap.sh/product-manager)
I hope that aspiring or practicing Product Managers find this post and enjoy!

1,888,219 | Middleware and Interceptors in NestJS: Best Practices | NestJS is a progressive Node.js framework for building efficient and scalable server-side... | 0 | 2024-06-14T10:04:12 | https://dev.to/ezilemdodana/middleware-and-interceptors-in-nestjs-best-practices-5923 | nestjs, backend, typescript, middleware | NestJS is a progressive Node.js framework for building efficient and scalable server-side applications. Among its many powerful features, middleware and interceptors stand out as essential tools for handling cross-cutting concerns in a clean and reusable manner. In this article, we'll explore the concepts of middleware and interceptors, their use cases, and best practices for implementing them in your NestJS applications.
**Middleware in NestJS**
What is Middleware?
Middleware functions are functions that have access to the request and response objects, and the next middleware function in the application's request-response cycle. Middleware can perform a variety of tasks, such as logging, authentication, parsing, and more.
**Creating Middleware**
In NestJS, middleware can be created as either a function or a class implementing the **NestMiddleware** interface. Here’s an example of both approaches:
**Function-based Middleware**
```
import { Request, Response, NextFunction } from 'express';
export function logger(req: Request, res: Response, next: NextFunction) {
console.log(`Request...`);
next();
}
```
**Class-based Middleware**
```
import { Injectable, NestMiddleware } from '@nestjs/common';
import { Request, Response, NextFunction } from 'express';
@Injectable()
export class LoggerMiddleware implements NestMiddleware {
use(req: Request, res: Response, next: NextFunction) {
console.log('Request...');
next();
}
}
```
**Applying Middleware**
```
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { logger } from './common/middleware/logger.middleware';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
app.use(logger);
await app.listen(3000);
}
bootstrap();
```
To apply middleware to specific routes, use the configure method in a module:
```
import { Module, NestModule, MiddlewareConsumer } from '@nestjs/common';
import { LoggerMiddleware } from './common/middleware/logger.middleware';
import { CatsController } from './cats/cats.controller';
@Module({
controllers: [CatsController],
})
export class CatsModule implements NestModule {
configure(consumer: MiddlewareConsumer) {
consumer
.apply(LoggerMiddleware)
.forRoutes(CatsController);
}
}
```
**Use Cases for Middleware**
- Logging: Log requests for debugging and analytics.
- Authentication: Check if a user is authenticated before proceeding.
- Request Parsing: Parse incoming request bodies (e.g., JSON, URL-encoded).
**Interceptors in NestJS**
**What is an Interceptor?**
Interceptors are used to perform actions before and after the execution of route handlers. They can transform request/response data, handle logging, or modify the function execution flow.
**Creating Interceptors**
Interceptors are implemented using the NestInterceptor interface and the @Injectable decorator. Here’s an example of a basic interceptor:
```
import {
Injectable,
NestInterceptor,
ExecutionContext,
CallHandler,
} from '@nestjs/common';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';
@Injectable()
export class TransformInterceptor<T> implements NestInterceptor<T, any> {
intercept(
context: ExecutionContext,
next: CallHandler,
): Observable<any> {
return next
.handle()
.pipe(map(data => ({ data })));
}
}
```
**Applying Interceptors**
Interceptors can be applied globally, at the controller level, or at the route handler level.
**Global Interceptors**
To apply an interceptor globally, use the useGlobalInterceptors method in the main.ts file:
```
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { TransformInterceptor } from './common/interceptors/transform.interceptor';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
app.useGlobalInterceptors(new TransformInterceptor());
await app.listen(3000);
}
bootstrap();
```
**Controller-level Interceptors**
To apply an interceptor at the controller level, use the @UseInterceptors decorator:
```
import { Controller, Get, UseInterceptors } from '@nestjs/common';
import { TransformInterceptor } from './common/interceptors/transform.interceptor';
@Controller('cats')
@UseInterceptors(TransformInterceptor)
export class CatsController {
@Get()
findAll() {
return { message: 'This action returns all cats' };
}
}
```
**Route-level Interceptors**
To apply an interceptor at the route handler level, use the @UseInterceptors decorator directly on the method:
```
import { Controller, Get, UseInterceptors } from '@nestjs/common';
import { TransformInterceptor } from './common/interceptors/transform.interceptor';
@Controller('cats')
export class CatsController {
@Get()
@UseInterceptors(TransformInterceptor)
findAll() {
return { message: 'This action returns all cats' };
}
}
```
**Use Cases for Interceptors**
- Response Transformation: Modify response data before sending it to the client.
- Logging: Log method execution time and other details.
- Exception Mapping: Transform exceptions into user-friendly error messages.
- Caching: Implement caching mechanisms for repeated requests.
**Best Practices**
- Keep Middleware Lightweight: Middleware should be focused on tasks that need to be performed on every request, such as logging or authentication. Avoid heavy processing in middleware.
- Use Interceptors for Transformation: Use interceptors for transforming request and response data, logging execution time, and handling errors.
- Modularize Middleware and Interceptors: Create separate files and directories for middleware and interceptors to keep the codebase organized.
- Leverage Dependency Injection: Use NestJS's dependency injection system to inject services into middleware and interceptors.
- Avoid Redundant Code: Use global middleware and interceptors for tasks that need to be applied across the entire application, and use route-specific ones for more granular control.
**Conclusion**
Middleware and interceptors are powerful tools in NestJS that help you handle cross-cutting concerns effectively. By following best practices and understanding their use cases, you can create more maintainable and scalable NestJS applications. Whether you're logging requests, handling authentication, transforming responses, or caching data, middleware and interceptors provide the flexibility and control needed to build robust applications.

1,888,229 | Using ArgoCD & Terraform to Manage Kubernetes Cluster | Seamless deployment and management of your infrastructure and application is key for a successful... | 0 | 2024-06-14T10:02:32 | https://spacelift.io/blog/argocd-terraform | terraform, kubernetes, devops |
Seamless deployment and management of your infrastructure and application is key for a successful organization. This is where ArgoCD and Terraform can help.
Terraform is an infrastructure-as-code (IaC) tool that allows you to provision infrastructure and works with many cloud providers, databases, VCS systems, and Kubernetes. ArgoCD is a GitOps delivery tool for Kubernetes that uses git as its only source of truth for deploying and managing your Kubernetes workloads.
##Why use ArgoCD with Terraform
Using [ArgoCD](https://spacelift.io/blog/argocd) with [Terraform](https://spacelift.io/blog/what-is-terraform) combines infrastructure deployment with application deployment. By using them together, you can ensure a seamless process for your workflow.
Here are some key advantages of combining them:
- Declarative IaC and application management - Both tools have a declarative approach when it comes to managing the infrastructure and application, ensuring the current state matches the desired state.
- GitOps workflow-- You can achieve a GitOps workflow for both of them - out of the box for ArgoCD and with a specialized product for Terraform. In GitOps, git is used as the only source of truth, and you can easily handle your workflow and ensure everything is working smoothly.
- Consistency - By leveraging ArgoCD and Terraform, you can ensure the same configuration is deployed on different environments, reducing the chances for errors and discrepancies.
##Tutorial: How to manage Kubernetes cluster with ArgoCD and Terraform
Let's build an automation that showcases how to manage a K8s cluster with ArgoCD and Terraform.
### Prerequisites
For this automation, you need to have an AWS account, everything else will be built and shared during the tutorial. You can get the repository code [here](https://github.com/saturnhead/eks-argo-terraform).
### Step 1 - Prepare Terraform code for EKS
To ensure everything works smoothly, we will create all the components necessary to have an EKS cluster running:
- Network (VPC, Subnets, Route table, Internet Gateway)
- IAM (Role and Policies)
- Node Group
- EKS cluster
Network resources:
```
data "aws_availability_zones" "available" {}
resource "aws_vpc" "main" {
cidr_block = "10.0.0.0/16"
tags = {
Name = "main-vpc"
}
}
resource "aws_subnet" "public_subnet" {
count = 2
vpc_id = aws_vpc.main.id
cidr_block = cidrsubnet(aws_vpc.main.cidr_block, 8, count.index)
availability_zone = data.aws_availability_zones.available.names[count.index]
map_public_ip_on_launch = true
tags = {
Name = "public-subnet-${count.index}"
}
}
resource "aws_internet_gateway" "main" {
vpc_id = aws_vpc.main.id
tags = {
Name = "main-igw"
}
}
resource "aws_route_table" "public" {
vpc_id = aws_vpc.main.id
route {
cidr_block = "0.0.0.0/0"
gateway_id = aws_internet_gateway.main.id
}
tags = {
Name = "main-route-table"
}
}
resource "aws_route_table_association" "a" {
count = 2
subnet_id = aws_subnet.public_subnet.*.id[count.index]
route_table_id = aws_route_table.public.id
}
```
We are creating one VPC, two subnets for the EKS nodes, an internet gateway, and a route table with a rule to the internet gateway. We associate the route table with the two subnets.
Next, we create a node role and a cluster role:
```
locals {
policies = ["arn:aws:iam::aws:policy/AmazonEKSWorkerNodePolicy", "arn:aws:iam::aws:policy/AmazonEKS_CNI_Policy", "arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly"]
}
resource "aws_iam_role" "eks_cluster_role" {
name = "eks-role"
assume_role_policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
"Action": "sts:AssumeRole",
"Principal": {
"Service": "eks.amazonaws.com"
},
"Effect": "Allow",
"Sid": ""
}
]
}
EOF
tags = {
Name = "eks-role"
}
}
resource "aws_iam_role_policy_attachment" "eks_cluster_role_attachment" {
role = aws_iam_role.eks_cluster_role.name
policy_arn = "arn:aws:iam::aws:policy/AmazonEKSClusterPolicy"
}
resource "aws_iam_role" "eks_node_role" {
name = "eks-node-role"
assume_role_policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
"Action": "sts:AssumeRole",
"Principal": {
"Service": "ec2.amazonaws.com"
},
"Effect": "Allow",
"Sid": ""
}
]
}
EOF
tags = {
Name = "eks-node-role"
}
}
resource "aws_iam_role_policy_attachment" "eks_role_attachment" {
for_each = toset(local.policies)
role = aws_iam_role.eks_node_role.name
policy_arn = each.value
}
```
Finally, we create the EKS cluster and the EKS node group:
```
resource "aws_eks_cluster" "main" {
name = "main-eks-cluster"
role_arn = aws_iam_role.eks_cluster_role.arn
vpc_config {
subnet_ids = aws_subnet.public_subnet.*.id
}
tags = {
Name = "main-eks-cluster"
}
}
resource "aws_eks_node_group" "main" {
cluster_name = aws_eks_cluster.main.name
node_group_name = "main-eks-node-group"
node_role_arn = aws_iam_role.eks_node_role.arn
subnet_ids = aws_subnet.public_subnet.*.id
scaling_config {
desired_size = 2
max_size = 3
min_size = 1
}
tags = {
Name = "main-eks-node-group"
}
}
```
### Step 2 - Prepare the Terraform code that deploys ArgoCD
For this deployment, we will use the helm provider to deploy the ArgoCD Helm chart in our Kubernetes cluster. It will also deploy a load balancer to access it.
```
data "aws_eks_cluster_auth" "main" {
name = aws_eks_cluster.main.name
}
resource "helm_release" "argocd" {
depends_on = [aws_eks_node_group.main]
name = "argocd"
repository = "https://argoproj.github.io/argo-helm"
chart = "argo-cd"
version = "4.5.2"
namespace = "argocd"
create_namespace = true
set {
name = "server.service.type"
value = "LoadBalancer"
}
set {
name = "server.service.annotations.service\\.beta\\.kubernetes\\.io/aws-load-balancer-type"
value = "nlb"
}
}
data "kubernetes_service" "argocd_server" {
metadata {
name = "argocd-server"
namespace = helm_release.argocd.namespace
}
}
```
### Step 3 - Configure remote state
It is essential to keep your state in a remote location. You can learn more in our guide: [How to manage Terraform remote state](https://spacelift.io/blog/terraform-remote-state#benefits-of-using-terraform-remote-state).
For our example, we will use an S3 backend:
```
terraform {
required_version = "1.5.7"
backend "s3" {
bucket = "your-bucket-name"
key = "your-bucket-key"
region = "eu-west-1"
}
}
```
You will need to specify a bucket name, the region where the bucket can be found, and a name for your state file.
### Step 4 - Run the Terraform code
First, navigate to the directory that contains your Terraform code and run [*terraform init*](https://spacelift.io/blog/terraform-init).
```
terraform init
Initializing the backend...
Successfully configured the backend "s3"! Terraform will automatically
use this backend unless the backend configuration changes.
Initializing provider plugins...
- Finding latest version of hashicorp/aws...
- Finding latest version of hashicorp/kubernetes...
- Finding latest version of hashicorp/helm...
- Installing hashicorp/aws v5.50.0...
- Installed hashicorp/aws v5.50.0 (signed by HashiCorp)
- Installing hashicorp/kubernetes v2.23.0...
- Installed hashicorp/kubernetes v2.23.0 (unauthenticated)
- Installing hashicorp/helm v2.13.2...
- Installed hashicorp/helm v2.13.2 (signed by HashiCorp)
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
```
Let's apply the code:
```
terraform apply -auto-approve
...
Plan: 16 to add, 0 to change, 0 to destroy.
Changes to Outputs:
+ argocd_initial_admin_secret = "kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath={.data.password} | base64 -d"
+ argocd_server_load_balancer = (known after apply)
+ eks_connect = "aws eks --region eu-west-1 update-kubeconfig --name main-eks-cluster"
```
It takes about ten minutes for all the resources to be created.
```
Apply complete! Resources: 16 added, 0 changed, 0 destroyed.
Outputs:
argocd_initial_admin_secret = "kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath=\"{.data.password}\" | base64 -d"
argocd_server_load_balancer = "a53a6bf4abebe46f79da6179425ca5f4-7d359c1121a50305.elb.eu-west-1.amazonaws.com"
eks_connect = "aws eks --region eu-west-1 update-kubeconfig --name main-eks-cluster"
```
### Step 5 - Prepare the Kubernetes manifests to deploy a sample nginx application
In this step, we want to prepare the configuration that will be deployed with ArgoCD. We will create a simple nginx application that will output "Hello from Argo". For that, we will need a configmap, a deployment, and a service:
```
# confimap_yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: nginx-config
namespace: default
data:
index.html: |
<html>
<head><title>Hello from Argo</title></head>
<body>
<h1>Hello from Argo</h1>
</body>
</html>
```
In the [Kubernetes configmap](https://spacelift.io/blog/kubernetes-configmap), we save the index.html configuration file that will be used by our nginx deployment.
```
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
namespace: default
spec:
replicas: 1
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:latest
ports:
- containerPort: 80
volumeMounts:
- name: nginx-config-volume
mountPath: /usr/share/nginx/html
volumes:
- name: nginx-config-volume
configMap:
name: nginx-config
```
In the deployment file, we specify which containers we want to use (nginx in our case), and we mount our configmap to get the index.html file.
```
# service.yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-service
namespace: default
spec:
selector:
app: nginx
ports:
- protocol: TCP
port: 80
targetPort: 80
type: LoadBalancer
```
We will expose our application through a load balancer service.
### Step 6 - Create the ArgoCD application manifest
Before creating the manifest, we need to ensure that we push this code to a VCS repository. If you are using the repository I have provided, you can leave this file as it is. Otherwise, you should make it point to the correct repository.
The ArgoCD application manifest will look like this:
```
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: nginx-app
namespace: argocd
spec:
project: default
source:
repoURL: 'https://github.com/saturnhead/eks-argo-terraform'
targetRevision: HEAD
path: 'argocd/app'
destination:
server: 'https://kubernetes.default.svc'
namespace: default
syncPolicy:
automated:
prune: true
selfHeal: true
syncOptions:
- CreateNamespace=true
```
Now, we need to connect to our Kubernetes cluster. This can be done by running the following command:
```
aws eks --region eu-west-1 update-kubeconfig --name main-eks-cluster
```
Next, we can run our application manifest:
```
kubectl apply -f argocd-app.yaml
application.argoproj.io/nginx-app created
```
### Step 7 - Log in to Argo and see the application
To log in to Argo, we can use the outputs exposed by our Terraform code:
```
argocd_initial_admin_secret = "kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath={.data.password} | base64 -d"
argocd_server_load_balancer = "a53a6bf4abebe46f79da6179425ca5f4-7d359c1121a50305.elb.eu-west-1.amazonaws.com"
```
We need to get the initial ArgoCD admin secret, so we can run the first command for that:
```
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath=\"{.data.password}\" | base64 -d"
```
Now, open a browser and go to the argocd_server_load_balancer address:
Use admin as the username and provide the password you got when you ran the first command.
You should see your application healthy and synced. If you click on it, you will see all the resources that have been deployed with Argo:
If you want to access the application itself, select the nginx-service, go to the last line of the manifest, select the hostname, and paste it into your browser:

##Managing Kubernetes cluster with ArgoCD, Terraform, and GitHub Actions
Let's take the above automation to the next step and deploy it through a GitHub Actions pipeline to enable collaboration and ensure that you won't need to do anything manually.
We will build three different workflows:
1. Terraform deployment
2. ArgoCD application deployment
3. Tearing down the infrastructure and application
### Step 1 - Prerequisites
For all of these deployments, we need to define some GitHub Actions secrets for the AWS credentials. We need to use:
```
AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_REGION
AWS_SESSION_TOKEN
```
To add a secret to your repository, navigate to the repository's settings, select Secrets and Variables, and click on Actions.
### Step 2 - Prepare the Terraform creation workflow
You can find the workflow file [here](https://github.com/saturnhead/eks-argo-terraform/blob/main/.github/workflows/terraform_deployment.yaml).
This workflow will run on pull requests, and main branch merges whenever there are changes to the Terraform directory in the repository. For pull requests, it will also show the plan as a PR comment.
The workflow does the following:
1. Checks out the code
2. Sets up Terraform
3. Sets up the AWS credentials
4. Runs `terraform init`
5. Runs `terraform validate` to ensure the configuration is valid
6. Runs `terraform fmt` to check if the code is formatted correctly
7. Runs a `terraform plan` and comments on the plan on a PR only on pull requests
8. Runs a `terraform apply` on a master branch push
### Step 3 - Prepare the Argo creation workflow
The workflow file can be found [here](https://github.com/saturnhead/eks-argo-terraform/blob/main/.github/workflows/argo.yaml).
This workflow will run whenever the ArgoCD folder changes or when the Terraform workflow finishes successfully from the main branch.
It goes through the following steps:
1. Checks out the code
2. Verifies if the workflow was triggered from the main branch
3. Configures AWS credentials
4. Installs kubectl
5. Updates the kubeconfig
6. Deploys the application
### Step 4 - Prepare the destruction workflow [Optional]
The workflow file can be found [here](https://github.com/saturnhead/eks-argo-terraform/blob/main/.github/workflows/destroy.yaml).
It only runs manually and goes through the following steps:
1. Checks out the code
2. Sets up Terraform
3. Sets up the AWS credentials
4. Installs kubectl
5. Deletes the argocd application
6. Runs `terraform init`
7. Runs `terraform destroy`
### Step 5 - Trigger a run
Make a dummy change to your Terraform code and see the pipelines get triggered (I just added a new line).
##Managing Terraform & Kubernetes with Spacelift
To take your deployment to the ultimate level, you can easily leverage Spacelift.
Spacelift supports both [Terraform](https://docs.spacelift.io/vendors/terraform/) and [Kubernetes](https://docs.spacelift.io/vendors/kubernetes/) and enables users to create [stacks](https://docs.spacelift.io/concepts/stack/) based on them. Leveraging Spacelift, you can build CI/CD pipelines to combine them and get the best of each tool. This way, you will use a single tool to manage your Terraform and Kubernetes resources lifecycle, allow your teams to collaborate easily, and add some necessary security controls to your workflows.
### Step 1 - Build the stack automation
Let's build the same integration we built for GitHub actions. To automate as much as possible, I will create the deployment stacks using [OpenTofu](https://spacelift.io/blog/what-is-opentofu):
```
provider "spacelift" {}
terraform {
required_providers {
spacelift = {
source = "spacelift-io/spacelift"
}
}
}
resource "spacelift_stack" "K8s-cluster" {
branch = "main"
description = "Provisions a Kubernetes cluster"
name = "Terraform Kubernetes Cluster"
project_root = "terraform"
repository = "eks-argo-terraform"
terraform_version = "1.5.7"
labels = ["terraform-argocd"]
}
resource "spacelift_stack" "argocd" {
kubernetes {
namespace = "argocd"
}
branch = "main"
description = "Deploys an ArgoCD application"
name = "ArgoCD application"
project_root = "argocd/config"
repository = "eks-argo-terraform"
labels = ["terraform-argocd"]
before_init = ["$AWS_LOGIN"]
}
resource "spacelift_aws_integration_attachment" "K8s-cluster" {
integration_id = var.integration_id
stack_id = spacelift_stack.K8s-cluster.id
read = true
write = true
}
resource "spacelift_aws_integration_attachment" "argocd" {
integration_id = var.integration_id
stack_id = spacelift_stack.argocd.id
read = true
write = true
}
resource "spacelift_stack_dependency" "cluster-argo" {
stack_id = spacelift_stack.argocd.id
depends_on_stack_id = spacelift_stack.K8s-cluster.id
}
resource "spacelift_stack_dependency_reference" "output" {
stack_dependency_id = spacelift_stack_dependency.cluster-argo.id
output_name = "eks_connect"
input_name = "AWS_LOGIN"
}
```
We are creating two stacks that will leverage an existing cloud integration for AWS (this will generate dynamic credentials), and we will build a stack dependency between them. The Terraform stack will deploy the Kubernetes cluster and ArgoCD as before, and the K8s stack will depend on it and receive the kubeconfig login command as an output. The stacks will leverage the same code as before.
You can check out how to configure your own cloud integration [here](https://docs.spacelift.io/integrations/cloud-providers/aws).
### Step 2 - Create the stack inside Spacelift
Let's create this stack inside Spacelift. First, go to Stacks and select Create Stack:
Then, select the repository and the path to the Spacelift configuration:
Next, select the tool you want to use to provision the resources. We will use OpenTofu, but you can use Terraform instead:
Next, in the Define Behavior tab check the Administrative option. This will let you provision Spacelift resources inside your account:
Skip to Summary and finish the stack creation wizard. Before running the code, we need to add the environment variable for the cloud integration ID that will be passed to both configurations (Terraform and K8s). This can be done from the Environment tab. Ensure the variable name is prefixed with "TF_VAR". The integration_id is the id of the integration that you've previously built by following the documentation.
### Step 3 - Create the Terraform and K8s stacks using the admin stack
Now, we are ready to run the code. Return to the Tracked runs tab and trigger a run.
Confirm the run and wait for the resources to be created. The apply should take less than ten seconds:
Next, if you go to your stacks, you should see two new stacks created:
### Step 4 - Run the Terraform Kubernetes cluster stack and wait for its dependencies to be triggered
Now, you can either trigger a run directly on the Terraform Kubernetes cluster stack, or change the Terraform code. For simplicity, let's just trigger a run as we did before:
We can see all the resources that will be created in our infrastructure. Let's confirm the run and let's check the K8s stack until the apply finishes and see what is happening with it:
As you can see, this one has a run queued and is waiting for the Terraform stack to finish before applying.
The Terraform stack finished running, and the run on the K8s one was triggered:
A few seconds after confirming the run, the resource is created:
To see the outputs from the Terraform stack, we can navigate back to the Terraform stack and select the Outputs tab:
We can log in to the Argo instance by repeating the process we've done before, logging in to the K8s cluster, getting the initial admin secret, and navigating to the argocd server load balancer:
##Key points
In this post, we've covered how to use Terraform with ArgoCD and shown how the deployment can be configured.
Deploying from a local environment will not work if you are collaborating with multiple engineers, and using GitHub Actions can prove complicated --- especially when configuring the pipeline itself. Using Spacelift, you benefit from out-of-the-box workflows for your favorite infrastructure tools, and you can easily build dependable workflows.

HPFS is a file metadata server based on Ceph RADOS, designed to address the bottleneck issues commonly encountered in Ceph file systems. Unlike traditional setups that rely on third-party storage for metadata, HPFS directly stores metadata on RADOS. This approach ensures metadata stability akin to that of Ceph, which has undergone over a decade of iterative development and is known for its robust data stability. By avoiding third-party plugins for metadata storage, we eliminate potential security risks associated with external data handling. One of the known shortcomings of Ceph is the single-point issue with its Metadata Server (MDS), which tends to underperform in high IOPS scenarios. HPFS has redesigned the metadata architecture to create a distributed framework, allowing metadata access to scale with the concurrent access capabilities of RADOS objects. Additionally, HPFS has been specifically optimized for scenarios involving intensive small file operations, such as AI visual training and graphic rendering, significantly enhancing IOPS performance under multi-client and concurrent conditions—often outperforming CephFS by orders of magnitude. If you manage environments with hundreds of millions of files requiring frequent metadata access, consider evaluating the performance of HPFS. We have now made some of HPFS’s features available for free to facilitate community interaction and collaborative discussion.

Whether you're an individual concerned about personal privacy or a professional protecting your intellectual property, finding your photos on the internet is a crucial task. This is where face recognition search engines come into play. These advanced tools utilize sophisticated algorithms to identify and track images across the web, providing an efficient way to locate your photos online. In this blog post, we'll explore how to find your leaked and republished photos on the internet and delve into the workings of face recognition search engines, helping you take control of your digital footprint.
## What is a face recognition search engine?
A face recognition search engine is a specialized type of search tool designed to identify and match human faces within a database of images or videos. This technology leverages advanced algorithms and artificial intelligence to analyze facial features and characteristics, such as the distance between the eyes, the shape of the nose, and the contours of the cheekbones. By converting these features into a unique digital signature or template, the system can quickly compare and match faces across large datasets.
These search engines are utilized in a variety of applications, ranging from security and surveillance to social media and personal photo organization. In security settings, face recognition can help identify individuals of interest, such as suspects or missing persons, by scanning footage from surveillance cameras and matching it against a database. On social media platforms, this technology enables features like automatic tagging of friends in photos.
The process typically begins with the detection phase, where the system identifies and isolates faces within an image or video frame. Following this, the recognition phase involves extracting facial features and creating a unique profile for each face. Finally, the matching phase compares these profiles against a database to find possible matches.
As face recognition technology continues to evolve, it is increasingly incorporating elements like deep learning and neural networks to enhance accuracy and efficiency.

The application of technology is enabled and made possible by cloud computing.
A simple instance is the alarm on your phone. This alarm, after being created was made available to users through cloud computing. The applications we use daily and the recently hyped innovations of ChatGPT and Gemini.AI are made available and accessible to users because of cloud computing.
It enables apps to synchronize data and manage services.
Commuting to work with maps relies on cloud computing. Your Microsoft 365 and Google Workspace are made possible because of cloud computing.
Here, we will understand cloud computing and how it helps distribute data and processes across multiple machines.
Here, we will describe the concept of cloud computing, explain the cloud delivery and service models, describe cloud computing for your purpose, and more.
We will also understand the fundamentals of cloud computing, cloud service models, infrastructure as a service, serverless computing, risks and benefits of cloud computing.
## Cloud Delivery Models
Cloud Delivery models are also called cloud sourcing models and there are varying computing models.
**Local:** Traditionally, we would have our applications on a local machine like your laptop, containing all the data and software necessary for a particular task on that same machine with or without an internet connection.
The advantage is that the solution is cheap, fast, and readily available. And when there is no internet connection, it is pretty safe from outside attackers. The downside is that it is not easy to work collaboratively and the resources of a local machine might not be sufficient for extensive datasets. This is why many organizations store their data and install software not on local machines but on servers to which organizations can connect.
**On-premise:** On-premise means an organization owns hardware like servers located in the organization's rooms or geographically close by to the organization. However, if the organization decides to move to the cloud, the organization will no longer own the hardware but render it from a cloud service provider. These servers were physically located within the rooms owned by the organization hence the name, on-premise or on-prem computing. The advantages are that the organizations have complete control of the software and infrastructure. On the downside, this setup has limited scalability and high investment costs. All resources must be purchased by the organization and installed on the servers entering the cloud.
**Private Cloud:** This means infrastructure is reserved for a particular organization and we can connect to the service via a network as opposed to the public which requires the internet.
We can also use virtual private networks to establish a connection.
This is dependent on whether the hardware is reserved for organizations in the data centers run by the cloud service provider reserved for the organization only.
**Public Cloud:** In contrast to private cloud, if the organization decides to use the public cloud, the organization would share the resources with other cloud users. Another difference is that the public uses the internet while the private cloud uses a non-public network.
**Hybrid cloud:** This model uses a mixture of on-premise and cloud services/machines. This way, we can choose which data should be stored, processed, and analyzed in the cloud and what should remain in the organization's machines.
**Multi-Cloud:** This means that the organization uses cloud services provided by other cloud providers.
Using different services offered by more than one cloud provider. Eg, we can use storage services provided by both providers A and B but only processing services by cloud A and analytical services by provider B. This way we might avoid vendor-locking and select from a wide range of services the ones that are useful for our particular use case. One drawback is that these setups are more complex to manage.
**Poly-Cloud:** This means that we use one type of service by one cloud provider only eg, we would use a database by provider A and analytical services by provider B. Here, we use only the services by one cloud provider for one specific domain of the project. Eg, we would store all the data in Cloud A, process the data in Cloud B, and analyze the data in Cloud C.
Cloud-native is not a delivery model but implies that an application is developed with the cloud in mind from the very beginning. Eg, it is designed to be easily scalable, reliable, and available by deploying it to a cloud environment eg as microservices and containers, or as a serverless function.
## Fundamental Roles in Cloud Computing
**Cloud Solution Architect:** This is also called cloud enterprise architect is responsible for designing a high-level concept aligned with a business strategy. Coming up with a cloud architecture to scale the organization. It deals with business understanding and technologies.
**Cloud Architect:** This is similar to the cloud solution Architect but is more focused on the implementation unlike the Cloud solution which is focused on the high-level concept of the architecture, the cloud architect is more focused on the hands-on implementation of that concept into concrete services that work together. They are specialized in the offerings of one or a few cloud providers.
**Cloud engineers:** they are the administrators and operators of the cloud systems. They maintain the cloud system and its services. They manage servers and clusters. They are not only responsible for the administration of the entire system but also individual services. This includes access control. They understand operating systems and server maintenance.
**Cloud developers:** They are programmers using cloud services in the applications they develop. This includes application developers because they do not come up with new cloud services but use the provided services and configure them in their applications. They use and orchestrate cloud services in their applications. They need knowledge of how the cloud systems are set up. However, their core is programming, API setup, and networking.
**Cloud consultant:** this is similar to the cloud solution architect. They offer advice, and guidance and provide an objective overview of cloud providers. They understand the organization's business and cloud needs and come up with solutions and architecture. They are more focused on added value for business processes.
Sometimes, these roles overlap and they can function to aid the other.
## Cloud Service Models
Cloud service models are different from cloud delivery models.
This tells how responsibilities are shared between the cloud provider and us as the users/developers.
**On-prem:** We have complete control of the system but it also brings in a lot of responsibility of taking care of each component.
**Bare-metal-as-a-service(BAAS):** we might choose to not own physical hardware but get it from a provider responsible for maintenance. But why not give the provider responsibility for hardware virtualization? This is the next one called IAAS.
**Infrastructure-as-a-service(IAAS):** the cloud provider is responsible for the physical hardware and virtualization while users are responsible for everything that runs on top of that virtualized hardware. This means flexibility but also maintenance responsibility. Eg for the application code that we develop for these virtualized machines. example AWS EC2, Azure virtual machines, and GCP compute engines.
**Container-as-a-service(CAAS):** when cloud providers offer services to run containers and are responsible for maintaining all underlined components, it is called CAAS. eg Azure container instance, Azure Kubernetes serves, AWS elastic container service, AWS elastic Kubernetes service, Google Cloud run, and Google kubernetes engine.
**Platform as a service (PAAS):** Here, in addition to hardware and virtualization, the cloud provider is also responsible for the operating system and runtime executing the code we develop. Here the provider is responsible for the maintenance responsibility and the runtime to the provider. Examples are storage services like AWS S3, Azure block storage, and GCP block storage. Managed database storage like AWS dynamoDB and Azure Cosmos DB and IOT services like AWS IOT core, Azure IOT hub, and GCP cloud IOT core. As the name suggests, PAAS is all about providing a platform.
**Serverless also called Function and a service (FAAS):** It is similar to the platform as a service, however, it also implies that we are not busy maintaining and configuring any hardware but focus entirely on code development. We simply push our code to a serverless service to be executed in the cloud and we do not think about the underlined infrastructure at all.
Here, it is not so much about the platform being provided but the framework on which we can execute our application code and not on setting up and maintaining the underlined component.
Examples are AWS Lambda, Azure functions, and GCP Cloud functions.
**Software as a service(SAAS):** In addition to the hardware virtualization, operating system, and runtime, the provider is also responsible for the application code in this service model. An example is Office 365 or any other similar cloud-based software. All we can change in this service are the application settings but not its code. Here we use functional software and can not change anything in it except the application settings.
## Risk and Advantages of Cloud Computing
## Advantages
**Cost reduction:** It is cheaper than local or on-premise solutions. The cost of purchasing hardware and hiring specialized staff better scale to the many cloud customers than having all this cost for one organization only. Also, many services are offered as pay-as-you-go billing models. This means that we can quickly adapt the cost of our system to the load it experiences.
Also, we can start with cheap hardware and quickly scale to bigger or more machines in the cloud. We can also save costs by running processes with lower priority when machines in data centers are idol because other customers do not use them at that time.
**Scalability:** Because cloud providers dispose of many machines, we can scale instantaneously and unlimitedly on the cloud by adding more or bigger machines to a running cluster.
**Flexibility:** As there are no upfront costs, we can try out new services and change components of our system easily.
**Easy access:** You only need a few clicks and buttons to spin up instances of the available technology in the cloud.
**Reliability:** Being distributed systems with high data replication and parallelization makes cloud computing highly reliable. Also, all cloud providers clearly define service level agreements and we are reimbursed if these agreements are not fulfilled.
**Physical safety:** it is an advantage as there is much stricter surveillance of physical access to the data centers than to the servers of a single organization.
Certificates: All cloud providers hold standardized certificates supporting us in evaluating the applied data security and protection standards. This also helps us choose appropriate providers for given use cases.
## Risk
**Expenses:** there can be additional expenses eg when resources are not adapted to need or we over-provision our services.
Redundancy in the system ensuring its reliability means additional network transfer. When not set up correctly, this can lead to unnecessary expenses. The good thing is that all cloud providers offer monitoring tools and automated alerts to mitigate these risks.
**Security:** When not set up correctly, it can be insecure. Of course, there can be more points of failure in a complex cloud system but depending on the service model, we might also give responsibilities to specialized units of the cloud provider with more workforce and higher security budget than single organizations.
**Share responsibility:** although this is usually considered a good thing, it can pose a risk. Independent of the cloud service model we choose, we will always be responsible for the stored data, the endpoint to our system, and the access management.
Also, legally, we always need clarity on how things are done by the cloud provider when handling personally identifiable information.
**Certifications and transparency:** Certifications are usually a good thing but the number of different certificates sometimes makes it difficult to understand what they mean and if they are worth something and applicable to a particular use case.
**Data Sovereignty:** This is important when handling personal data in the cloud. here, we must keep control of the data all the time. Eg, when the data is about a certain group of people, we must ensure that it never leaves the group of people.
